* Encryption data at-rest db-config
Description
diff-1: Handle 'force' updates to encryption_at_rest db-config
Major changes proposed:
1. Introduce 'encryption_data_at_rest_mode" 'configure new'
option to enable Encryption data at-rest. The feature is disabled
by default.
2. The configuration is meant to be set at the time of database
creation, addition checks will be done to avoid updating the config
in subsequent PR.
3. DatabaseConfiguration validity check to account for "tenant_mode"
set to `required` if Encryption data at-rest is selected given
EncryptionDomain matches Tenant boundaries.
