### What changes were proposed in this pull request?
This PR introduces new fields in Table and Partition thrift structs. These
fields are optional and currently HMS does not set these fields by default.
However, such fields are useful for non-hive SQL engines to integrate their
metadata cache over with HMS API. For example, see IMPALA-10612.
### Why are the changes needed?
See description above.
### Does this PR introduce _any_ user-facing change?
It introduces new optional fields to the Table and Partition objects. These
should not impact any current installations for HMS clients.
### How was this patch tested?
From hive's perspective the testing was manual. In order to test this
functionality, we would need to have some component which has ability to send
the filemetdata over HMS API. This is not available currently in Hive but there
were tests introduced in IMPALA-10612 to test the basic end-to-end
functionality of this feature.
