This is important when using gossiping ring. If source ingester is not leaving yet, than claiming its tokens will fail (merge function will not move ownership to the target ingester), and target ingester will end up with no tokens in the ring.

In order to work with gossiped ring correctly, ingester that is going to claim tokens from a different ingester needs to make sure that leaving ingester is indeed in the LEAVING state. Otherwise claiming tokens will fail. This change implements the check.
(Plus it also adds ring to prometheus metrics in distributor)
