Reduce noise in the provision logs

Reduce verbosity in order to shorten logs and make them more readable.

In two cases we just remove the verbose flag.

In one other case we undo inlining of a huge script in the command line.
Because we run the provisioning scripts in trace mode, this caused the
script to be logged, and it was rather long and meaningless since it
comes from an external project.
