Cleanup query keys output of Admin tool

1) Previously when the value bytes can't be deserialized it errored out
immediately and it does not print values of other nodes. You can do node
by node, but failed nodes can never be retrieved. Now if it fails, byte
array output will be printed.
2) When node does not have a key, it printed invalid metadata
exceptions for all other nodes. Now they are skipped in the output.
3) Does not report what all nodes had same value and which ones
differed.
add store-update command in new admin tool
Fixing the query-key in the new admin tool

I made the fix to the old tool incorrectly. Ported the code to the new
tool with no modification. Talked to Xu and merging this directly

Also added a minor fix to the unit tests which fails sometimes because
of error. Added some retries and ignoring the failure.

Fix getmetadata shell command

The "getmetadata" command cannot be run because the "get" command is
shadowing it.

slops are not pushed when cluster state changes

Slop pusher caches the cluster state from the server startup.
When the cluster state changes it is not refreshed.
When the node is marked down because of failures, since the failure
detector does not know about these new nodes, it never polls them back
for availability. The node is permanently marked down, until the server
reboots in which case the cluster is refreshed.

Added a way to run integration tests from gradle, but they are still not
part of any junit, junitAll or other tests.
