IMPALA-6448: Re-enable kerberized testing with KRPC

For the patch for IMPALA-5054, we realized that we needed to make
the kudu::rpc::Messenger configurable. A patch was done on the Kudu
side which is tracked by KUDU-2228. As part of that patch, one of
the design decisions taken was to only allow kerberos either on or
off for the entirety of the process life. This means that we cannot
switch kerberos on and off in the same process any more with KRPC.
This behavior can be found in SaslInit() in kudu/rpc/sasl_common.cc
as SaslInit() which is called once per process will hard code some
configuration which cannot be toggled.

This affected our kerberized rpc-mgr-tests. This patch splits out
the kerberized part of rpc-mgr-test into rpc-mgr-kerberized-test.

It also puts the common code between both the files into
rpc-mgr-test-base.h

> This makes the testing a little more complicated since we use a Gtest switch to switch between kerberos and plain SASL.
>  
> A fix for this is to split out kerberized testing from rpc-mgr-test into a new file and keep all the common code in rpc-mgr-test-base.
