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.
