HIGH: [Public] Make all workspace room members "known" to the admins

[quinthar]

Problem:
A workspace owner pays for activity in their workspace room. And anybody can invite anyone to that room. When you do, it notifies admins that someone has been invited in the #admins room. However, because the admins have no relationship with the invited person, the invited person shows as "Hidden".

Solution:
If Alice invites Bob to a room, and Cathy is the workspace admin, then Cathy should "know" Bob and see Bob's primary login. After all, Alice could have only invited Bob using Bob's primary login, so by inviting him, she's in effect introduced Bob to Cathy.

P.S. Is everyone reading this sure this is really a near-term priority? Be brave: if you disagree, go ahead and close it out. If someone disagrees, they'll reopen it, and if they don't: one less thing to do!
