[Notifications] Send out a notification on @mentions in Issue Activity tab Comments

[Fwang36]

Problem Statement

Filing a feature request on behalf of a user in this zendesk ticket

Our Issues Activity section allows for tagging users and teams. We should also send a notification when a user or team has been tagged in an issue.

Right now it seems we only send out a workflow notification if a user is subscribed to the issue (by default). At which point, they will receive a notification for every comment, regardless of whether they were tagged or not. Tagging them seems to provide no extra functionality in terms of notifications.

Solution Brainstorm

Send a new type of notification for being tagged. If a user has "Only Subscribed Issues" set in their notification settings, they should probably still be notified when tagged on an issue they are not subscribed to.

Or at least tagging a user should Subscribe that user to the issue if the user has "Only Subscribed Issues" in their settings

We have some upcoming work planned to improve notifications in general, I'll share this with the team.
