[Schem-Service] Schema service Integraion tests are failing in azure environment

The integration tests for schema service are failing with: Error code: 500- Internal server error. This failure is happening due to CosmosDB containers not being in correct shape. The current cosmos db containers for schema service, i.e. Source, Authority, EntityType and SchemaInfoStore are created with partition key as id, while it should be dataPartitionId

WIP for fixing this.
