provide a way to update repository before publish

[Rocco83]

The current behavior of cvmanager is to not take care of sw repository.
The truth is that we should have hopefully a repo sync just before the CV publish

Also, sometimes the repo sync may be not enough (see, any new added repo has to be added to sync plan).

A correct approach would be allowed to run a synchronization against:

• All of the repo belonging to the organization (simple one)
• All of the repo belongin to the CV in subject of the publish

The second one is much effective, but it is probably more challanging.

I'd love to see this as well, /cced.
