BCI-2588: Changes for STOM

[augustbleeds]

With these changes, STOM works locally.

STOM is basically a service that will pull config data from a http endpoint & environmental variables to determine what contracts to monitor. Then it will publish data to a local prometheus http server it creates and kafka topic.

Briefly, here's what I did

1. Run soak test in terminal 1
2. Modify ENV vars & /tmp/config directory with values of Link address, Ocr address, Proxy address
3. In terminal 2, start config http server
4. In terminal 3, start kafka server (docker compose up)
5. Wait until the ocr rounds start
6. In terminal 4, source ENV vars in step 2 and start the monitoring service

Now that we know the monitoring plugin and relayer integration works smoothly locally, I'll create a ticket for testnet deployment to make sure that the

1. http config files are updated
2. kafka topic is still provisioned
3. monitoring k8s deployment is deployed
