The 'Expect: 100-continue' http header allows http clients to send
only the headers for their request, get a confirmation back from the
server that the headers are valid, and only then send the body of the
request, avoiding the overhead of sending large requests that will
ultimately fail.
This patch adds support for this in the HS2 HTTP server by having
THttpServer look for the header, and if it's present and the request
is validated returning a '100 Continue' response before reading the
body of the request.
It also adds supports for using this header on large requests sent by
impala-shell.
Testing:
- This case is covered by the existing test_large_sql, however that
test was previously broken and passing spuriously. This patch fixes
the test.
- Passed all other shell tests.

This is a prelimary patch that simply copies THttpClient.py from
Thrift master into Impala, changes imports as appropriate, and adjusts
the formatting from 4 spaces to 2 spaces.
This is to allow us to make modifications to THttpClient in future
patches. There are no functional changes in this patch.

The patch adds a set of scripts for converting the impala-shell
into a true distributable python package. The package can be
installed using familiar python commands, e.g.:
$ python setup.py (install|develop)
or
$ pip install -e /path/to/dist/dir
The entry point script, make_python_package.sh, will run as a
part of the standard sequence of steps that results from calling
buildall.sh, and will produce a gzipped tarball inside of
Impala/shell/dist as an artifact. Thereafter, make_python_package.sh
can be run manually any time.
The expectation is that an official maintainer would need to manually
upload official releases to the Python Package Index as appropriate.
