Insights/map type backend

Created by: coury-clark

Adds a search provider for the code insights backend to query against ComputeText. Note: we are going to have to make some changes based on feedback from the search team around how we interface with Compute, so this might be considered temporary.

Currently the query parser will break the compute query by dropping the content field. Manually add that into the queued job to test / use this for the time being.
