Fix for 1862 verbosity options for quicksetup tools

The fixes are just cosmetic.  They consist basically of:

* Add verbosity options for the uninstall and upgrade utilities and make them behave as the verbosity options of the setup.

* Make the output of the upgrader consistent with the output of setup and uninstall.

* Update the non verbose output of the import LDIF and the import automatically generated data so that a point is displayed every 3 seconds during the import is ongoing.  This way the user will not have the impression that the setup is blocked and we show that some work is going on.
