Hide maintenance mode behind a feature flag
Otherwise we'd lose mixed version cluster compatibility.
We cannot pre-create a table since it will be checked for existence
on cluster peers.
We cannot use an upgrade function since it assumes a cluster-wide
restart.
A feature flag avoids as many headaches as possible and when
flags are detected to be compatible on node start, they are
all enabled automatically.
