IMPALA-8832: Fix HTTP client protocol to work with Apache Knox

This patch fixes two bugs with Impala's HTTP client protocol:
- THttpServer transports are no longer wrapped in TBufferedTransports.
  THttpServer already has its own support for buffering to process one
  HTTP request at a time, and wrapping it in a TBufferedTransport
  interferes with this, in some cases causing client requests to
  either not be processed or to recieve multiple responses.
- Fixes a bug in THttpTransport where when a chunked HTTP request is
  finished being processed, the 'readHeaders_' variable is never reset
  and further requests over the connection are not processed.

Testing:
- Tested by proxying beeline connections to Impala through Apache Knox
