At startup, before the first check, Run removes from the loaded state
the domain, hostname and certificate entries of names no longer in
DNSWATCHER_TARGETS, so the dashboard, /api/v1/status and the startup
notification count only configured names. A configured domain's own
records, saved as a hostname entry under its name, are kept. Nothing is
notified. Each port check, next to the removal of stale port entries,
now also removes the certificate entries for an address a name no
longer resolves to, except while none of its nameservers answered, as
port entries already were.
