Description

Recently a dependabot commit has landed on connectors that upgrades the version of protobuf-java to 3.6.1

I think that we should revert that.

Part of the HBase 2 public API is that the public coprocessors use HBase 2 for communication.
See https://hbase.apache.org/book.html#cpeps

Using unshaded 3.6.1 in the connector breaks that contract.

The shaded connector artifacts do not include protobuf-java, so the change is effectively a NOOP for the shaded connector JAR.

However, in case someone depends on the core artifact, the change in the protobuf-java version may cause problems.

rajeshbabu  I know that you have added the explicit dependency for the table metadata broadcast featrue, and that you've applied the dependabot PR, but I think that we should stick to the protobuf pulled in by HBase.
