Set umask

Ensure we have a known-good umask.  Otherwise files such as
/etc/polkit-1/rules.d/50-libvirt-$STACK_USER.rules may not be readable
by non-root users afterwards.

Also reworded some comments to be more clear.

Add optional ionice to volume clearing process

Allow the volume clearing process to have an ionice priority set to
reduce the performance impact of volume zeroing. Note that this may
cause volume clearing processes to get backed up on  a busy system, use
with care.
