Operator email list

[charlesbrandt]

On the User Management page, add a button at the bottom of the page called something like "Operator Email List". Clicking on the button would show a modal dialog with a text area that includes a list of all email addresses of the operators, separated by commas. This would help when needing to send an announcement to all operators of the instance

The operators already have emails set up in their profiles. Alternatively, we could show a list of operator names that can either included / excluded from a "notifications group".

One way to handle this is by adding a "user groups" feature where users can belong to different groups. Each group could have extra details about how notifications are handled (like email or Slack, how often they're sent, and how urgent they are, like major issues, warnings, etc.). We also need to decide who can make, change, or delete these groups. We don't have to do all of this right now, but thinking about it now will make it easier to add new features later when we need to.
