Fixes Yokozuna integration tests

In the first case you now need to pause before trying to set bucket properties
or the bucket props operation will fail telling you the index doesn't exist.

In the second case you now have to pause before deleting or you get
back an error saying the index is not found.
Fix search MR test

Same issue as other tests. Need pauses to allow the index to
exist.
YZ index creation now deterministic

Based on the feedback from @coderoshi I went back and changed to
using a polling mechnism to wait for the YZ index to be created for
the various tests that need it.
