wzhou-code 397d1d15a2 IMPALA-10745: Support Kerberos over HTTP for impala-shell ...

This patch ports the implementation of GSSAPI authentication over http
transport from Impyla (https://github.com/cloudera/impyla/pull/415) to
impala-shell.

The implementation adds a new dependency on 'kerberos' python module,
which is a pip-installed module distributed under Apache License Version
2.
When using impala-shell with Kerberos over http, it is assumed that the
host has a preexisting kinit-cached Kerberos ticket that impala-shell
can pass to the server automatically without the user to reenter the
password.

Testing:
 - Passed exhaustive tests.
 - Tested manually on a real cluster with a full Kerberos setup.
