since that goes into the config and api (AFAICS), i'd not use spaces in 
the value. we could use 'read-only' for example, but maybe check other
parts of the api/configs where we may have values similar to this

i think we could combine the message + type in the enum, we just have
to manually to the deserialization (look for example how we
do the media-location for tapes, there we can have a named 'vault'
which gets (de)serialized as/from "vault-NAME"

we could to the same here with "read-only-foo' and 'offline-foo'

this would make for a nicer api maybe? (any other opinions @thomas 
@wolfgang @dietmar?)

also i think the way it is now, i could update the maintenance message 
without setting a mode...
