Cherry-pick of PR #21759 to 7.x branch. Original message:
What does this PR do?
Make API address and Shard ID required in Cloud Foundry settings.
Why is it important?
Having an auto-generated Shard ID leads to duplicated data when trying to scale, increasing the problems of loaded systems. Forcing to set a shard ID makes the user more conscious of the implications of this setting.
API address should be set in a real deployment.

Use cases
With previous default configuration, if someones tries to scale by adding a new instance, with the default configuration, they will use a different shard ID, effectively duplicating the data, and the load of the system.
Making the shard ID mandatory forces the user to be more conscious on the implications of this setting.
