Rework server_auto_join to use a timer instead of the peer count.
...
It is perfectly viable for an admin to downsize a Nomad Server cluster
down to 1, 2, or `num % 2 == 0` (however ill-advised such activities
may be). And instead of using `bootstrap_expect`, use a timeout-based
strategy. If the `bootstrapFn` hasn't observed a leader in 15s it will
fall back to Consul and will poll every ~60s until it sees a leader.

Shuffle all datacenters vs only the nearest N datacenters.
...
Per discussion, we want to be aggressive about fanning out vs possibly
fixating on only local DCs. With RPC forwarding in place, a random walk
may be less optimal from a network latency perspective, but it is guaranteed
to eventually result in a converged state because all DCs are candidates
during the bootstrapping process.

Bump various Consul search limits
...
Client: Search limit increased from 4 random DCs to 8 random DCs, plus nearest.
Server: Search factor increased from 3 to 5 times the bootstrap_expect.
This should allow for faster convergence in large environments (e.g.
sub-5min for 10K Consul DCs).

Reconcile, clean up, and centralize API version numbers (major and minor).
...
Reduce future confusion by introducing a minor version that is gossiped out
via the `mvn` Serf tag (Minor Version Number, `vsn` is already being used for
to communicate `Major Version Number`).
