Move the SmartScope workflow to the REST API.

[JoQCcoz]

The imaging workflow currently directly initiates a connection to the database. This sometimes yield odd connection issues and crashes the workflow. The idea is to route all of the database calls thought the REST API. There are many advantages to this change:

• Clear distinction between the imaging workflow and the webserver/database services.
• Would allow to break the code into master and worker and effectively deploy in that manner without too much duplication.
• Reduce crashes with database connection being dropped.
