Michael Ho 8d7f638654 IMPALA-7212: Removes --use_krpc flag and remove old DataStream services ...

This change removes the flag --use_krpc which allows users
to fall back to using Thrift based implementation of DataStream
services. This flag was originally added during development of
IMPALA-2567. It has served its purpose.

As we port more ImpalaInternalServices to use KRPC, it's becoming
increasingly burdensome to maintain parallel implementation of the
RPC handlers. Therefore, going forward, KRPC is always enabled.
This change removes the Thrift based implemenation of DataStreamServices
and also simplifies some of the tests which were skipped when KRPC
is disabled.

Testing done: core debug build.
