draft: notify auto-dns during reboots
Paired with the mininag retirement (team#41734 (closed)), this will ensure hosts get removed from rotation when we reboot them.
There are many problems here:
-
the zonefile gets rebuilt too often -
code is duplicated between the ganeti and non-ganeti cases (an already existing problem -
not sure i like the good=True API -
we should do this for all hosts, as this will take forever, we need a way to check if a host is a mirror, presumbaly in LDAP
