Prepare dashboard for a new metadata package file structure.

New file structure allows for using same form definition file for
several services. Fields 'type', 'name' and 'description' are taken
from form definition file, as before, but now these fields should be
inferred from 'full_service_name', 'service_display_name' and
'description' fields, appropriately, from service manifest by metadata
repository.
