The current implementation of the DNS challenge does not allow
to set multiple TXT records at once.
As PowerDNS has the concept of record sets, and so all records
for the same type and name must set during one call, we would override
existing records.
To avoid this, we merge the new TXT record with existing ones
After removing the challenge record from OVH, the zone itself
does not get refreshed and leaving the obsolete record in place.
Calling '/domain/zone/ZONE/refresh' after deleting the record will
apply the changes to the zone.
Added the option to provide the gcloud service account as a string via the environment variable `GCE_SERVICE_ACCOUNT` in addition to the already available option to specify a filepath to a keyfile `GCE_SERVICE_ACCOUNT_FILE`.
