Ensure that PATransportChannel delegates to wrapped channel and add tests

[cwperks]

Ensures that PATransportChannel delegates implementations to the wrapped channel except for:

• getChannelType
• getProfileName

Added tests that use reflection to ensure that if the TransportChannel interface changes that the CI in this repo catches it to ensure that this wrapper class gets modified accordingly.

The BWC tests are failing, can you bump up the BWC version to 2.11 here: https://github.com/opensearch-project/performance-analyzer/blob/main/build.gradle#L13. The same needs to be back-ported to 2.x branch.
