gpfs volume driver backup file access fixes

Changes to volume file permission settings require a temporary
chown to the file being backed up.

Also, use gpfs file clone copy mechanism to create a consistent
file copy so that the TSM backup service can create a hard link
to the clone file.

remove _check_container_exists from Swift backup driver

The HTTP PUT on a Swift container is idempotent, we don't need to
check if it exists before uploading a backup.

This fixes a side issue where swiftclient was printing a TRACE of
the failed HTTP HEAD, previously in use to check if the container
existed.
