minor: Enabling streaming writes to metadata code paths only when eligible metadata partitions

[nsivabalan]

Describe the issue this Pull Request addresses

We added streaming writes to metadata table in 1.1.0. Not all partitions in mdt supports streaming writes as of now. So, fixing writes to leverage streaming writes to metadata table only when eligible metadata partitions are enabled.

Summary and Changelog

• Leverage streaming writes to metadata table in spark only when either of RLI (global or non global) or secondary index is enabled.

Impact

• Avoids the new dag if not really required. Down the line, when we move col stats and other partitions to streaming flow, probably we will get rid of this optimization.

Risk Level
