Sargun Dhillon 7a1618ced3 Add quota support to VFS graphdriver
This patch adds the capability for the VFS graphdriver to use
XFS project quotas. It reuses the existing quota management
code that was created by overlay2 on XFS.

It doesn't rely on a filesystem whitelist, but instead
the quota-capability detection code.
