Patch api for Partition service
This change addresses the issue #2 (closed). Patch API will be able to update existing partitions. This includes:
- Update existing properties (same key, changing 'sensitive' field or changing 'value' field)
- Add new properties
Does not include deletion of properties. To do that, we would have to delete and re-create the partition.
To add this API, we also need to change to Redis based cache as VM cache causes inconsistencies when number of instances are more than 1.
Will follow up with a core-common change to add api to the client library.
