Update glance image size limit
The image size limit for glance using the unified limits is
set to 1000MB (~1GB). This is pretty low given that a volume's
minimum size is 1GB and when uploaded to glance fills out the
whole limit.
The limit issue can also be seen by a recent tempest change[1]
where uploading two volumes failed[2] across various jobs due
to this limit.
We do have a config option in devstack
``GLANCE_LIMIT_IMAGE_SIZE_TOTAL`` but that will need to be
configured for various jobs and a 2GB seems to be a sensible
default which this patch configures.
