  1. ring/util: allow waiting for ring stability with good state transitions 

    In some use cases, such as the store gateway, it is enough for the
user to know that the token distribution didn't change and it is not
important to know if some member changed between allowed states.

This patch implements the new WaitRingTokensStability function to
be able to wait for tokens stability and ignore allowed state changes.

The original motivation was that store gateway tests took a minute longer
then strictly necessary.
