feat: Add a flag for role that installs account app
Created by: eesaanatluri
This will let us turn the account app on or off during the build.
Currently, we need this so that we can build an OOD image with the account app turned off because users should be directed to the account app running on login005, but not the one on the OOD VM. This will also let us decouple the account app from OOD so that it can be run as a standalone service.
