The problem is that if you just stop the service, it not only removes it
from scheduling, but it stops it from receiving updates to floating IP
changes, interface changes, etc. I think it would be nice to have a way to
explicitly stop it from being scheduled new routers, but still act as a
functioning L3 agent otherwise.
