[FLINK-5496] [mesos] Relocate Mesos Protobuf dependency to avoid version
conflicts
This PR is based on #3155.
Only relocate Mesos Protobuf dependency in flink-mesos. This avoids
problems with Mesos
because Flink pulls in Protobuf 2.5.0 via Flakka.

$ git pull https://github.com/tillrohrmann/flink mesosFixRelocation

[FLINK-5495] [mesos] Provide executor to ZooKeeperMesosWorkerStore
The ZooKeeperMesosWorkerStore instantiates a ZooKeeperStateHandleStore
which requires an
Executor instance. This executor is now given to the
ZooKeeperMesosWorkerStore.

> When using the Mesos' HA mode, one cannot start the Mesos appmaster, because

> It seems as if the {{flink-mesos}} module relocates the curator dependency in
> another namespace than {{flink-runtime}}. Not sure why this is done.
