Add pacmd/pactl command to set volumes by role

From the Debian bug tracker:
there is no way to control volume of system sounds by script with pacmd (eg. at login). Sometimes system sounds are much too loud. Then you have to start pavucontrol (if installed) and move the system sound slider to reduce sound volume. Or you have to switch off the sound card. This is a no-go for disabled people.
Please implement access to control system sound volume in pacmd or another command line tool.
And indeed, currently there is no command line interface to set volumes by role.
