Add stack for azimuth watchers with gateway-server (#379)

* Setup gateway-server with watchers

* Add js script to merge toml config files

* Remove individual watcher configs

+# Azimuth Watcher
+
+Instructions to setup and deploy Azimuth Watcher stack
+
+## Setup
+
+Prerequisite: ipld-eth-server RPC and GQL endpoints
+
+Clone required repositories:
+
+```bash
+laconic-so --stack azimuth setup-repositories
+```
+
+NOTE: If the repository already exists and checked out to a different version, `setup-repositories` command will throw an error.
+For getting around this, the `azimuth-watcher-ts` repository can be removed and then run the command.
+
+Checkout to the required versions and branches in repos
+
+```bash
+# azimuth-watcher-ts
+cd ~/cerc/azimuth-watcher-ts
+git checkout v0.1.0
+```
+
+Build the container images:
+
+```bash
+laconic-so --stack azimuth build-containers
+```
+
+This should create the required docker images in the local image registry.
+
+### Configuration
+
+* Create and update an env file to be used in the next step:
+
+  ```bash
+  # External ipld-eth-server endpoints
+  CERC_IPLD_ETH_RPC=
+  CERC_IPLD_ETH_GQL=
+  ```
+
+* NOTE: If ipld-eth-server is running on the host machine, use `host.docker.internal` as the hostname to access host ports
+
+### Deploy the stack
+
+* Deploy the containers:
+
+  ```bash
+  laconic-so --stack azimuth deploy-system --env-file <PATH_TO_ENV_FILE> up
+  ```
+
+* List and check the health status of all the containers using `docker ps` and wait for them to be `healthy`
+
+## Clean up
+
+Stop all the services running in background run:
+
+```bash
+laconic-so --stack azimuth deploy-system down
+```
+
+Clear volumes created by this stack:
+
+```bash
+# List all relevant volumes
+docker volume ls -q --filter "name=.*watcher_db_data"
+
+# Remove all the listed volumes
