-------------------------------------------
1.9 backport:
{noformat}
commit 70291edf09f5b35af2b5389024de84b550ccacf3
Author: Andrei Sekretenko <asekrete...@apache.org>

Fixed handling disconnected agents by REACTIVATE_AGENT call.
This patch fixes MESOS-10116 by preventing REACTIVATE_AGENT from
activating disconnected agents in the allocator and also fixes the
handling of agents that were removed while the reactivation was being
stored into the registry.
