support compression on pinot broker

Use-case: we are deploying pinot to small ec2 instances (t3.medium) with limited network capacity (0.25 gbit on stable load). Request pattern is to get raw data within time period. Average response size is 900 kb (uncompressed). We would like broker to compress the data so we are not facing VM network bandwidth limit so fast.

This parameter could be optional on the broker server configuration file.

Thanks!

Start by locating Pinot's broker response path and the broker server configuration described in the issue. Determine how optional compression should be configured and verify that raw-data requests return compressed responses without changing their contents.
