Subject: [PATCH] Partial Fix LP #992640 - Extend volume group

Tempest's volume list tests create a number of 1G
volumes, but devstack's default volume backing file
size is only 2G. If tempest is being executed, we
set VOLUME_BACKING_FILE_SIZE=4g in localrc, enabling
Tempest's volume tests to succeed without cryptic
error messages...
