Add "Associated domain(s)" field

[WhamboMPS]

Email aliases are created for specific needs that are usually associated with one (or more than one) domains. For instance, I have created an alias with the prefix of msft on my custom domain (MSFT is the ticker symbol for Microsoft). I could conceivably use [email protected] when registering at microsoft.com but also at hotmail.com, github.com, linkedin.com, etc. since all these businesses/domains are owned by Microsoft. And there are definitely times when you need to answer the question "What email alias did I use at domain xyz?" Therefore,

Please create an Associated domain(s) field that exists in a many-to-one relationship with an Alias. This field should appear on the New Custom Alias page (see #566) and should also appear on the dashboard cards. It is critical that this field be searchable from the freeform text field on the Dashboard.

If labels and tags are added, you would probably be able to create tags for the domains.
