Alan Bishop 30ca49bf61 Add ability to deploy glance at DCN/Edge sites
This patch adds two new tripleo services that together support
deploying the glance-api service at edge sites. The service uses the
same glance database in the control plane, but allows other edge
services (e.g. cinder and nova) to access a glance endpoint that is
local to the edge site.

A new GlanceApiEdge service is a minor variant of the GlanceApi
service. The most significant change is it doesn't use the control
plane VIP, but instead configures cinder and nova services to access
the glance-api endpoint running on that edge node (not the VIP).

A companion HAproxyEdge service supports scaling out DCN sites with
larger (>3) number of nodes. Instead of deploying GlanceApiEdge on
every node, the HAproxyEdge service configures a local haproxy to
forward glance-api requests to the edge nodes running GlanceApiEdge.

The HAproxyEdge is extensible. While this patch is only concerned
with proxying glance-api, it can be extended to support additional
proxy requirements as needs arise.
