In general, in the case where there is no cinder v1 endpoint created
(or deleted - use openstack service delete cinder to reproduce) certain
volume related menu entries are not displayed
This patch add a a new function to check cinder v2/v3 endpoints instead
of only checking the v1 endpoint in instance launch model.
Also, in the image panel, instead of checking v1 endpoint,
it should check v2 and v3 as well.
