jasonmfehr f2f6b4b580 IMPALA-11375 Impala shell outputs details of each RPC ...

When the Impala shell is using the hs2 protocol, it makes multiple RPCs
to the Impala daemon.  These calls pass Thrift objects back and forth.
This change adds the '--show_rpc' which outputs the details of the RPCs
to stdout and the '--rpc_file' flag which outputs the RPC details to the
specified file path.

RPC details include:
- operation name
- request attempt count
- Impala session/query ids (if applicable)
- call duration
- call status (success/failure)
- request Thrift objects
- response Thrift objects

Certain information is not included in the RPC details:
- Thrift object attributes named 'secret' or 'password'
  are redacted.
- Thrift objects with a type of TRowSet or TGetRuntimeProfileResp
  are not include as the information contained within them is
  already available in the standard output from the Impala shell.

Testing:
- Added new tests in the end-to-end test suite.
