Augment GET /users internal API endpoint search functionality

What would you like to see!

Deliverables

• [x] the "search users" internal API endpoint should also use the search term to search based on the name of any teams that the user currently belongs to (case insensitive)
• [x] Authentication wise we should augment the endpoint such that it can be consumed by the Incident plugin
• [x] Update integration tests
• [x] Endpoint should be visible, and documented, in our Swagger docs (will make it much easier for the Incident team to understand the endpoint)
• [x] Response - we should augment the response schema to add the following items:
  • [x] is the user currently on-call for at least one schedule? (can likely be a simple boolean for now; double check with Incident/Design team)
  • [x] list of teams the user is currently a member of
