Sync process utils from olso

This change syncs in:

33afb20 Fix broken formatting of processutils.execute log statement
5e3d3a5 Mask passwords included without quotes at the ends of commands
6751b30 Remove extra whitespace

The most important part is '33afb20' which was broken in nova after
the last oslo sync.
