volume: add new option -o o=noquota

add a new option to completely disable xfs quota usage for a volume.

xfs quota set on a volume, even just for tracking disk usage, can
cause weird errors if the volume is later re-used by a container with
a different quota projid.  More specifically, link(2) and rename(2)
might fail with EXDEV if the source file has a projid that is
different from the parent directory.

To prevent such kind of issues, the volume should be created
beforehand with `podman volume create -o o=noquota $ID`
