Remove redundant IndexProvider config now that host is shared

Now that host is shared having separate config for listen and announce addresses along with graphsync limit makes no sense since all of that is shared with the markets host and datatransfer manager.
Use the same host and datatransfer as markets for index provider

 # Lotus changelog

-# v1.13.0-rc1 / 2021-10-06
+# v1.13.2 /  2022-01-09

-This is the first release candidates for lotus v1.13.0, a recommended lotus release that supports the upcoming 
+Lotus v1.13.2 is a *highly recommended* feature release with remarkable retrieval improvements, new features like 
+worker management, schedule enhancements and so on. 
+
+## Highlights
+- 🚀🚀🚀Improve retrieval deal experience
+  - Testing result with MinerX.3 shows the retrieval deal success rate has increased dramatically with faster transfer 
+    speed, you can join or follow along furthur performance testings [here](https://github.com/filecoin-project/lotus/discussions/7874). We recommend application developers to integrate with the new 
+    retrieval APIs to provide a better client experience.
+  - 🌟🌟🌟 Reduce retrieval Time-To-First-Byte over 100x ([#7693](https://github.com/filecoin-project/lotus/pull/7693))
+    - This change makes most free, small retrievals sub-second
+  - 🌟🌟🌟 Partial retrieval ux improvements ([#7610](https://github.com/filecoin-project/lotus/pull/7610))
+    - New retrieval commands for clients:
+      - `lotus client ls`: retrieve and list desired object links
+      - `lotus client cat`: retrieve and print the data from the network
+    - 🌟🌟 The monolith `ClientRetrieve` method was broken into:
+      - `ClientRetrieve` which retrieves data into the local repo (or into an IPFS node if ipfs integration is enabled)
+      - `ClientRetrieveWait` which will wait for the retrieval to complete
+      - `ClientExport` which will export data from the local node
+      - Note: this change only applies to v1 API. v0 API remains unchanged.
+    - 🌟 Support for full ipld selectors was added (for example making it possible to only retrieve list of directories in a deal, without fetching any file data)
+      - To learn more, see [here](https://github.com/filecoin-project/lotus/blob/0523c946f984b22b3f5de8cc3003cc791389527e/api/types.go#L230-L264)
+- 🚀🚀 Sealing scheduler enhancements ([#7703](https://github.com/filecoin-project/lotus/pull/7703),
+  [#7269](https://github.com/filecoin-project/lotus/pull/7269)), [#7714](https://github.com/filecoin-project/lotus/pull/7714)
+  - Workers are now aware of cgroup memory limits
+  - Multiple tasks which use a GPU can be scheduled on a single worker
+  - Workers can override default resource table through env vars
+    - Default value list: https://gist.github.com/magik6k/c0e1c7cd73c1241a9acabc30bf469a43
+- 🚀🚀 Sector storage groups ([#7453](https://github.com/filecoin-project/lotus/pull/7453))
+  - Storage groups allow for better control of data flow between workers, for example, it makes it possible to define that data from PC1 on a given worker has to have it's PC2 step executed on the same worker
+  - To set it up, follow the instructions under the `Sector Storage Group` section [here](https://lotus.filecoin.io/docs/storage-providers/seal-workers/#lotus-worker-co-location)

+# v1.13.0 / 2021-10-18
+
+Lotus v1.13.0 is a *highly recommended* feature release for all lotus users(i.e: storage providers, data brokers, application developers and so on) that supports the upcoming 
 [Network v14 Chocolate upgrade](https://github.com/filecoin-project/lotus/discussions/7431).
-This feature release includes latest functionality and improvements, like data transfer rate-limiting, rust-proof-ffi experimental CUDA support and so on. We *highly recommend* users like storage providers, data brokers, and so on upgrading your nodes and all subsystems to this release!
-
-> Note: This release candidate sets the upgrade epoch for calibration net, however, it does not set the Network v14 
-> Chocolate upgrade for mainnet. FIPs(FIP0020-0025) included are based on optimistic acceptance, things may well 
-> change according to the result of FIP last calls.
+This feature release includes the latest functionalities and improvements, like data transfer rate-limiting for both storage and retrieval deals, proof v10 with CUDA support, etc. You can find more details in the Changelog below.

 ## Highlights
 - Enable separate storage and retrieval transfer limits ([filecoin-project/lotus#7405](https://github.com/filecoin-project/lotus/pull/7405))
+    - `SimultaneousTransfer` is now replaced by `SimultaneousTransfersForStorage` and `SimultaneousTransfersForRetrieval`, where users may set the amount of ongoing data transfer for storage and retrieval deals in parallel separately. The default value for both is set to 20. 
+    - If you are using the lotus client, these two configuration variables are under the `Client` section in `./lotus/config.toml`.
+    - If you are a service provider, these two configuration variables should be set under the `Dealmaking` section in `/.lotusminer/config.toml`.
 - Update proofs to v10.0.0 ([filecoin-project/lotus#7420](https://github.com/filecoin-project/lotus/pull/7420))
- update to go-graphsync v0.10.0
+    - This version supports CUDA. To enable CUDA instead of openCL, build lotus with `FFI_USE_CUDA=1 FFI_BUILD_FROM_SOURCE=1 ...`.
+    - You can find additional Nvidia driver installation instructions written by MinerX fellows [here](https://github.com/filecoin-project/lotus/discussions/7443#discussioncomment-1425274) and perf improvements result on PC2/C2/WindowPoSt computation on different profiles [here](https://github.com/filecoin-project/lotus/discussions/7443), most people observe a 30-50% decrease in computation time.

+- Feat/datamodel selector retrieval ([filecoin-project/lotus#6393](https://github.com/filecoin-project/lotus/pull/66393393))
+    - This introduces a new RetrievalOrder-struct field and a CLI option that takes a string representation as understood by [https://pkg.go.dev/github.com/ipld/go-ipld-selector-text-lite#SelectorSpecFromPath](https://pkg.go.dev/github.com/ipld/go-ipld-selector-text-lite#SelectorSpecFromPath). This allows for partial retrieval of any sub-DAG of a deal provided the user knows the exact low-level shape of the deal contents.
+        - For example, to retrieve the first entry of a UnixFS directory by executing, run `lotus client retrieve --miner f0XXXXX --datamodel-path-selector 'Links/0/Hash' bafyROOTCID ~/output`
 - Expose storage stats on the metrics endpoint ([filecoin-project/lotus#7418](https://github.com/filecoin-project/lotus/pull/7418))
 - feat: Catch panic to generate report and reraise ([filecoin-project/lotus#7341](https://github.com/filecoin-project/lotus/pull/7341))
+    - Set `LOTUS_PANIC_REPORT_PATH` and `LOTUS_PANIC_JOURNAL_LOOKBACK` to get reports generated when a panic occurs on your daemon miner or workers.
 - Add envconfig docs to the config ([filecoin-project/lotus#7412](https://github.com/filecoin-project/lotus/pull/7412))
+    - You can now find supported env vars in [default-lotus-miner-config.toml](https://github.com/filecoin-project/lotus/blob/master/documentation/en/default-lotus-miner-config.toml).

+# v1.12.0 / 2021-10-12
+
+This is a mandatory release of Lotus that introduces [Filecoin Network v14](https://github.com/filecoin-project/community/discussions/74#discussioncomment-1398542), codenamed the Chocolate upgrade. The Filecoin mainnet will upgrade at epoch 1231620, on 2021-10-26T13:30:00Z. 
+
+The Chocolate upgrade introduces the following FIPs, delivered in [v6 actors](https://github.com/filecoin-project/specs-actors/releases/tag/v6.0.0)
+
+- [FIP-0020](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0020.md): Add return value to `WithdrawBalance`
+- [FIP-0021](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0021.md): Correct quality calculation on expiration
+- [FIP-0022](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0022.md): Bad deals don't fail PublishStorageDeals
+- [FIP-0023](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0023.md): Break ties between tipsets of equal weight
+- [FIP-0024](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0024.md): BatchBalancer & BatchDiscount Post-HyperDrive Adjustment
+- [FIP-0026](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0026.md): Extend sector faulty period from 2 weeks to 6 weeks
+
+Note that this release is built on top of lotus v1.11.3. Enterprising users like storage providers, data brokers and others are recommended to use lotus v1.13.0 for latest new features, improvements and bug fixes.
+
+## New Features and Changes
+- Implement and support [FIP-0024](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0024.md) BatchBalancer & BatchDiscount Post-HyperDrive Adjustment: 
+  - Precommit batch balancer support/config ([filecoin-project/lotus#7410](https://github.com/filecoin-project/lotus/pull/7410))
+    - Set `BatchPreCommitAboveBaseFee` to decide whether sending out a PreCommits in individual messages or in a batch.
+    - The default value of `BatchPreCommitAboveBaseFee` and `AggregateAboveBaseFee` are now updated to 0.32nanoFIL.
+- The amount of FIL withdrawn from `WithdrawBalance` from miner or market via lotus CLI is now printed out upon message landing on the chain.
+
+## Improvements
+- Implement [FIP-0023](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0023.md) (Break ties between tipsets of equal weight)
+  - ChainStore: Add a tiebreaker rule for tipsets of equal weight ([filecoin-project/lotus#7378](https://github.com/filecoin-project/lotus/pull/7378))
+- Randomness: Move getters from ChainAPI to StateAPI ([filecoin-project/lotus#7322](https://github.com/filecoin-project/lotus/pull/7322))
+
+## Bug Fixes
+- Fix Drand fetching around null tipsets ([filecoin-project/lotus#7376](https://github.com/filecoin-project/lotus/pull/7376))
+
+## Dependency Updates
+- Add [v6 actors](https://github.com/filecoin-project/specs-actors/releases/tag/v6.0.0)
+  - **Protocol changes**
+     - Multisig Approve only hashes when hash in params
+     - FIP 0020 WithdrawBalance methods return withdrawn value
+     - FIP 0021 Fix bug in power calculation when extending verified deals sectors
+     - FIP 0022 PublishStorageDeals drops errors in batch
