Clint Armstrong 4ef8543128 Permit workers to override resource table 
In an environment with heterogenious worker nodes, a universal resource
table for all workers does not allow effective scheduling of tasks. Some
workers may have different proof cache settings, changing the required
memory for different tasks. Some workers may have a different count of
CPUs per core-complex, changing the max parallelism of PC1.

This change allows workers to customize these parameters with
environment variables. A worker could set the environment variable
PC1_MIN_MEMORY for example to customize the minimum memory requirement
for PC1 tasks. If no environment variables are specified, the resource
table on the miner is used, except for PC1 parallelism.

If PC1_MAX_PARALLELISM is not specified, and
FIL_PROOFS_USE_MULTICORE_SDR is set, PC1_MAX_PARALLELSIM will
automatically be set to FIL_PROOFS_MULTICORE_SDR_PRODUCERS + 1.

Architecture

high-level architecture

Manager

Manages is the top-level piece of the storage system gluing all the other pieces together. It also implements scheduling logic.

package stores

This package implements the sector storage subsystem. Fundamentally the storage is divided into paths, each path has it's UUID, and stores a set of sector 'files'. There are currently 3 types of sector files - unsealed, sealed, and cache.

Paths can be shared between nodes by sharing the underlying filesystem.

stores.Local

The Local store implements SectorProvider for paths mounted in the local filesystem. Paths can be shared between nodes, and support shared filesystems such as NFS.

stores.Local implements all native filesystem-related operations

stores.Remote

The Remote store extends Local store, handles fetching sector files into a local store if needed, and handles removing sectors from non-local stores.

stores.Index

The Index is a singleton holding metadata about storage paths, and a mapping of sector files to paths

LocalWorker

LocalWorker implements the Worker interface with ffiwrapper.Sealer and a store.Store instance
