Convert long running SSE HTTP processing into database driven process

[dogeared]

Ideally, when the long running endpoint: /api/v1/updateAndEmail is hit, the controller would return immediately with a process id.

The async service method would be kicked off as normal. Regular updates could be made to a record in the database to indicate progress. This table should include a progress or status field that would be marked complete when the long-running process is done.
