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

> Project: IMPALA
> Issue Type: Bug
> Components: Clients
> Affects Versions: Impala 3.3.0
> Reporter: Thomas Tauber-Marshall
> Assignee: Thomas Tauber-Marshall
> Priority: Blocker
> Labels: security
>
> Impala recently added support for HTTP clients over HS2. One of the motivations for this work was to allow proxying of connections to Impala through other services such as Apache Knox.
> However, testing in testing with Knox, it seems that its possible to connect to Impala successfully, but then queries fail to run or results aren't retrieved.
