Adjust frequency of alerts for monitored SSL/Websites

Currently there is no way to adjust the frequency of how alert emails are generated from Hudu when monitoring SSL/Domain expiration's. This causes a lot of extra tickets to be created in ticket systems for emails generated from Hudu. It would be beneficial to be able to configure the alerts to only generate once, or only generate once at 30 days, once at 15 days, once at 5 days etc.
