Add new field to TeamType to allow bot queries

Add a bot_query field to TeamType which will send queries to the
backend simulating tipline bot queries.

Initially, this is returning the most recent Explainers/FactChecks
as TiplineSearchResults, but eventually it will be hooked to the
actual bot implementation.
