Julie Pichon cf0aac9400 Support for Glance v2
Implements wrappers necessary for Horizon to work with either Glance
v1 or v2 and removes the dependency on the Glance v1 endpoint.
Handles the differences between setting properties with v1 and v2 and
restricts some Glance functions that aren't supported in v2.

Implements blueprint: horizon-glance-v2
