mc/c/metroctl: implement simple update sequencing

Adds support for the max-unavailable flag, specifying the number of
nodes which can be concurrently in the update process.

To implement this, we now wait for the node to report as healthy again
before considering the update complete.

This allows simple gradual cluster updates.
