Searching for agents - adding mentions of items not in drive scope

[joepio]

In the document editor, I'd like to be able to mention @Polleps. But I can't because the /query endpoint only searches in my current drive / hierarchy.

Some options:

Default search in current drive + all agents

• All agents can be messy / a lot. If a lot of agents are on your server, it will be messy.

Default search in all "my" drives + all agents

Front-end does a second query, specifically for agents

• We may need to change some indexing logic for this

IncludeAgents option in /query endpoint

• We only use this when doing a mention

Keep track of "friends" or "connections" somewhere

If we store user profiles in a drive context, we don't need custom search. But we'll do need to store profile data in drive scope.
