Review comment:
This is a good catch (to also response to other comments related) -->
technically speaking there should only be one ConfigKey in the JM/TM
perspective: the "REMOTE_KEYTAB_PATH", or previously known as "KEYTAB_PATH".
I would revert the changes I've done here. since if the keytab is shipped
over as you mentioned, it doesn't matter whether it is originated from a remote
ship location or pre-installed.
