mgr/cephadm: trigger host metadata refrsh when taking host out of maintenance

If a host was in maintenance mode, we should make sure to check
all of the host information again once it's taken out even if
it hasn't been long enough for the daemon/device/facts etc. cache
to timeout. Some users may make changes to things like the node's
hardware or OS during maintenance mode that we should make sure to
pick up as soon as possible
