 So it turns out that this menagerie of keys in prop224 was missing yet one
 more key in it :D.

 To extend to an introduction point, we need its onion key meaning we have
 to add it to the descriptor. Keep in mind that the client does NOT lookup
 the node in its consensus in order not to reveal which consensus it's
 using and avoid reachability issues with different consensus between
 service and client.

 This goes in two fold. First add an onion key field in the spec and then
 implement it in an extra commit in #20657 code (which is being reviewed).
 I would like us to avoid making a branch depending on 8k lines of code
 from another unmerged ticket.
