Make API address and Shard ID required in Cloud Foundry settings (ela…

…stic#21759) 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 always set in a real deployment. (cherry picked from commit 3e5a167)
