MNT: assess if value user checks should happen for all daq operations

[tangkong]

Raised during review of #203

          the check is only in restartdaq as people who start the DAQ may modify the configuration database and we wanted to make sure that some beamline scientists umask did not make the DAQ unusable for the next person on shift. This is not a problem for the new daq as far as I can see.

We should think about where we need these checks, but to roll this our before SC beam this may need to end up as a item for future review (like argpase versus getopt)
