Add epoch and backup workers to DBCoreState
...
This enables backup workers to know the end version of the epoch. Additionally,
the master recovery only needs to deal with crashed backup workers by
recruiting new workers to backup the unfinished version range.

If a process receives a message in its clusterControllerInterface before becoming the cluster controller, if the process does not become the cluster controller in the next minute it should destroy the interface to prevent a memory leak.

Wrap ClusterClientInterface into its own type
...
When a process joins a cluster it fetches the cluster
interface. However, not the whole interface is exposed
to the client. This mechanism relies on the fact that
the serializer keeps the field ordering and doesn't
verify the message before parsing it.
To make this work, we provide a client type with one
member (the ClusterInterface which is exposed to the
client and the server). This client interface has the
same FileIdentifier as the ClusterControllerFullInterface
which has the same first member. This works because
FlatBuffers allows for members to be missing.

Piggyback data distributor interface in worker registration
...
This allows cluster controller to know data distributor during worker
registration phase, thus avoiding recruiting a new data distributor after
starting.
Also change the worker to skip creating a new data distributor if there is
already one running on the worker, which can trigger operation timeout in tests.

Add a new DataDistributor role.
...
Let cluster controller to start a new data distributor role by sending a
message to a chosen worker.
Change MasterInterface usage in DataDistribution to masterId
Add DataDistributor rejoin handling.
This allows the data distributor to tell the new cluster controller of its
existence so that the controller doesn't spawn a new one. I.e., there should
be only ONE data distributor in the cluster.
If DataDistributor (DD) doesn't join in a while, then ClusterController (CC) tries
to recruit one as DD. CC also monitors DD and restarts one if it failed.
The Proxy is also monitoring the DD. If DD failed, the Proxy will ask CC for
the new DD.
Add GetRecoveryInfo RPC to master server, which is called by data distributor
to obtain the recovery Transaction version from the master server.

The master will tell the cluster controller if it is going to take a long time to recruit new logs in its DC; the cluster controller can determine if the other DC would be better and recruit there.
...
The cluster controller will not switch to the other data center if remote logs are too far behind.
We will not recruit in DCs with negative priority.
