    Thanks for the review @GJL. I've addressed your comments and rebased onto the latest master.
Merging once Travis gives green light.

>             Project: Flink
>          Issue Type: Bug
>          Components: Distributed Coordination
>    Affects Versions: 1.5.0
>            Reporter: Till Rohrmann

>              Labels: flip-6
>             Fix For: 1.5.0
> The {{SlotManager}} can reach an inconsistent state when a formerly free task slot is
reported as allocated by an incoming {{SlotReport}}. The problem is that the slot won't be
removed from the set of free slots and, thus, will be considered for future slot requests.
> The solution is to remove the slot from the set of free slots once it is reported allocated.
