Fix suggest zone to make sure the zone name is a dns component

[jschewebbn]

Need to include '.' before the name to keep from picking a zone based
on the end of the hostname that isn't the subdomain.

This fixes#30

[kindlich]

This would introduce another edge case:
Apex records/Root records (where the record's FQDN is the same as the zone's)

api_client=PDNSApiClient(...)
server=api_client.servers[0]
zone=server.create_zone('xxx.yyy.zzz.', ...)
# Would now return None instead of 'zone'server.suggest_zone('xxx.yyy.zzz.')

Though you could probably get around that by either checking for equality in a 2nd step or by prepending a . to the record as well 😉

Another way to implement this would be splitting like

defsuggest_zone(self, r_name: str):
LOG.info("suggesting zone for: %s", r_name)
ifnotr_name.endswith('.'):
raisePDNSCanonicalError(r_name)
best_match=Nonerecord_name_split=list(reversed(r_name.split('.')))
forzoneinself.pdns_server.zones:
zone_name_split=list(reversed(zone.name.split('.')))
ifzone_name_split==record_name_split[: len(zone_name_split)]:
ifnotbest_match:
best_match=zoneifbest_matchandlen(zone.name) >len(best_match.name):
best_match=zonelogger.info("zone best match: %s", best_match)
returnbest_match

I'm not sure, however, if this project is still maintained...
