When the domain was defined, its persistent domain definition wasn't
saved on disk, leading to the loss of all defined domains after a CH
driver restart.
Now all defined persistent domains are saved on disk and loaded
from disk during CH driver initialization. Saved domains now also can
be removed with undefine.
