Release 3.27.0 rc2

### Fixed Bugs:

- pm2 installation documentation error
- Use absolute paths with __dirname when adding processes
  to the ProcessSet instance

### Added Features:

- HTTP REST CRUD routes for all database tables
- Use express.Router instead of custom ResourcesRouter
- Enable Cross Origin Resource Sharing by default
I really don't like this repetition of response and error handling. Also defining the responses on the model/controller level, having it so tied in, will make it really hard to make consistent changes.
