Document number of required workers for Providers

[akshay-ap]

Is your feature request related to a problem? Please describe.
Provider has a code logic which checks if its the same provider or remote provider when starting compute job. For this it sends http request to the provider (which can be itself). If number of workers is 1 this leads to a race condition. There should be 2 minimum workers to avoid race condition.

Describe the solution you'd like
Document that number of workers should be 2 or more in deploying provider page.
