[FLINK-2409] [webserver] Replaces ActorRefs with ActorGateways in the web
servers
Replaces the `ActorRefs` used in the `WebInfoServer`, its servlets and the
`WebRuntimeMonitor` with `ActorGateways`. This provides automatic message
decoration. E.g. `Cancel` messages sent from the web interface are now
correctly wrapped in a `LeaderSessionMessage` and, thus, no longer make the
`JobManager` stop upon receiving the undecorated message.
Furthermore, this PR adds support for the new web interface with YARN.
The `FlinkMiniCluster` and its subclasses store now a reference to a
possibly started `WebMonitor` which allows the cluster to properly shut it
down, when the cluster is stopped.
