[FEATURE] Display SSL status on the "List websites" page

[Oceanwatcher]

It is a bit of work to figure out what domains that for some reason have a self signed SSL. You have to go to the website list, then to the overview for each domain. And for the mail domains, there is no way of knowing at all until you get an error when trying to send email as there is no mention on how many days the cert is valid.

This takes a lot of time. Especially if you have more than 2-3 domains for your customers.

It could be nice to add info about this on the list of websites:

• SSL Expire in 64 days - [ISSUE SSL]
• Mail SSL Expire in 364 days - [ISSUE SSL]

The * at the beginning of the line could be green for Let's Encrypt and red for self signed cert
