Description

Much like we rate limit slave removals in the common path (MESOS-1148), we need to rate limit slave removals that occur during master recovery. When a master recovers and is using a strict registry, slaves that do not re-register within a timeout will be removed.

Currently there is a safeguard in place to abort when too many slaves have not re-registered. However, in the case of a transient partition, we don't want to remove large sections of slaves without rate limiting.
