Provide destTeam parameter to rebalanceTeams again.

There is a wait before the load bytes of the dest team is used, so the
last commit inadvertently caused a behaviour change. Instead, update the
comment for the function, and pass const IDataDistributionTeam
references.

Use `clang-tidy -p . $file -checks='-*,modernize-use-override' -header-filter='.*' -fix`

those changes. This went pretty well for most files.
Formatting the following files went off the rails, so I'm going to

The mountainChopper and valleyFiller only move larger than average shards, to avoid moving high bandwidth shards which are generally smaller.

This is so that APIs that take priorities don't take ints, which are

Replace g_random and g_nondeterministic_random with functions deterministicRandom() and nondeterministicRandom() that return thread_local random number generators. Delete g_debug_random and trace_random. Allow only deterministicRandom() to be seeded, and require it to be seeded from each thread on which it is used.

Status: Use new data distributor worker to publish status
...
After we add a new data distributor role, we publish the data
related to data distributor and rate keeper through the new
role (and new worker).
So the status needs to contact the data distributor, instead of master,
to get the status information.

Fix a data movement stuck bug
...
When moving keys to a team, if one of the server in the target team died, then
the move can become stuck. This is because the DDTeamCollection waits for all
the data movement of the failed server to be completed. However, in this case,
because the movement has not finished yet, checking the database tells us there
is no key assocated with this server and it is safe to go ahead. In reality,
only the in-memory structure knows there is pending movement, i.e., unfinished
move causes some keys to be attributed to the failed server. Thus, the server
can't be removed yet. Fix by adding a check with in-memory structure in
waitForAllDataRemoved().
Use const& to optimize a few function parameters.

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.
