Tim Armstrong 8ee18c3b77 IMPALA-8659: Allow self-RPCs for KRPC to go via loopback ...

Adds a flag --rpc_use_loopback that causes two differences
in behaviour when enabled:
1. KRPC will listen on all interfaces, i.e. bind the socket
   to INADDR_ANY.
2. KRPC RPCs to --hostname are sent to 127.0.0.1 instead of
   the IP (maybe external) that --hostname resolves to.

There is no change in default behaviour, except in containers,
where this flag is enabled by default.

Testing:
* Added a custom cluster test, which runs in exhaustive,
  as a sanity test for the behaviour of the flag.
