Detect/notify about duplicate MarkMonitor domains
MarkMonitor can have multiple domain configurations with the same domain name:
{
'domainId': 3293101,
'domainName': 'wikimedia.ro',
'status': 'closed, already registered'
}
{
'domainId': 3335690,
'domainName': 'wikimedia.ro',
'status': 'registered locked'
}
This would have caused the second domain results to overwrite the first. We don't know result to trust, so instead we should just add this to the list of domains that require manual intervention in MarkMonitor.
