Add a new '--no-password' option to unset the password on an existing
server. In addition, add a new '--password' option that replaces the
interactive '--root-password' option. This makes sense given no other
commands uses interactive password options.
Checks that rely on specific API microversions now run before we execute
any action, to avoid situations where an update is only partially
applied.
