Landed for 2.4.1 and 2.5.0

A master patch for 233 can be seen here: http://review.whamcloud.com/7324

Test 185 is fixed in Master by http://review.whamcloud.com/#/c/6887/

[Keith Mannthey (Inactive)]

It seems both test_233 and test_185 failed and this is due to advanced features in the 2.4 server.

I setup some patches for 2.4 (and they should end up in Master) to do a quick mds server version check before running sanity test 233.
