cli,server: make quit/drain more friendly to clusters with many ranges

[jseldess]

PR: cockroachdb/cockroach#45149

From release notes:

It is now possible to drain a node without shutting down the process, using cockroach node drain. This makes it easier to integrate with service managers and orchestration: it now becomes safe to issue cockroach node drain and then separately stop the service via a process manager or orchestrator. Previously, there was a risk to misconfigure the service manager to auto-restart the node after it had shut down via quit, in a way that was surprising or unwanted. The new command node drain also recognizes the new --drain-wait flag. [#45149][#45149] {% comment %}doc{% endcomment %}
