move groups to user record for faster consistency

[byndcivilization]

Detailed Description

Currently _in_network and _groups are stored on the prospect record. This lags and also can be overwritten if a prospect is ingested but not processed. We need to move these arrays to the user record.

see bugs:

• https://github.com/advisorconnect/ui/issues/497

Possible Implementation

• [ ] ui-api
  • [ ] change search to pull groups and send to search
  • [ ] add fields to update route
• [ ] svc-search
  • [ ] search needs to feed in group array of prospect_ids rather than user_id
