I wasn't sure where the best place for buttons to go would be, but
Thomas Lamprecht suggested in [1] to place in the HA overview, so
that's where I figured it would fit best. I agree with his logic on
needing to check HA status before enabling/disabling the maintenance.
Selectable grid was an easy implementation there and the status was
already being polled.

Some copypasta got the best of me here. Will update for v2.

Oh, I didn't know that was possible. Will fix up this one and the next.
