Request how much free space in bytes is available on the disk/mountpoint
where folder resides
If a quota limit exists for this area, that will be taken
into account unless superuser is set to true.
If a user has exceeded the quota, a negative number can
be returned.
Note that the difference between total available space
and free space will not equal the combined size of the
contents on the file system, since the numbers for the
functions here are calculated from the used blocks,
including those spent on metadata and file nodes.
If actual used space is wanted one should use the
statistics functionality of ocean.io.vfs.
