----------------------------------------------

+1 LGTM. I reviewed the diff directly because I couldn't apply the patch cleanly on latest
master.

> {{SearchRateTrigger}} events are processed by {{ComputePlanAction}} and depending on
the condition either a MoveReplicaSuggester or AddReplicaSuggester is selected.
> When {{AddReplicaSuggester}} is selected there's currently a bug in master, due to an
API change (Hint.COLL_SHARD should be used instead of Hint.COLL). However, after fixing that
bug {{ComputePlanAction}} goes into an endless loop because the suggester endlessly keeps
creating new operations.
> Please see the patch that fixes the Hint.COLL_SHARD issue and modifies the unit test
to illustrate this failure.
