Steve Carlin bb9fb663ce IMPALA-10778: Allow impala-shell to connect directly to HS2 ...

Impala-shell already uses HS2 protocol to connect to Impalad.
This commit allows impala-shell to connect to any server (for
example, Hive) using the hs2 protocol. This will be done via
the "--strict_hs2_protocol" option.

When the "--strict_hs2_protocol" option is turned on, only features
supported by hs2 will work. For instance, "runtime-profile" is an
impalad specific feature and will be disabled.

The "--strict_hs2_protocol" will only work on servers that abide
by the strict definition of what is supported by HS2. So one will
be able to connect to Hive in this mode, but connections to Impala
will not work. Any feature supported by Hive (e.g. kerberos
authentication) should work as well.

Note: While authentication should work, the test framework is not
set up to create an HS2 server that does authentication at this point
so this feature should be used with caution.
