Spencer Smith 7719a67834 fix: refuse to upgrade if single master ...

This PR adds some simple logic to bail early in the upgrade process if
there only seems to be a single etcd node present in the cluster. This
allows us to keep from blowing up non-HA clusters if users issue an
upgrade command.

Will close #1770.
