A stack is an extremely heavyweight abstraction in Heat. Particularly in
TripleO, every stack includes a copy of all the template and environment
data for all of the stacks in the tree, all of which must be stored anew
in the database.
The EndpointMap abstraction created no fewer than 30 nested stacks, none
of which contained any resources but which existed purely for the
purpose of abstracting out some intrinsic functions used to calculate
the endpoint URLs for the various services. This likely adds several GB
to the memory requirements of the undercloud, and can cause things to
slow to a crawl since all 30 nested stacks need to be queried whenever
we need data from any one of them.
This change eliminates the nested stacks and instead generates the
endpoint map statically. This can be done offline in less than 250ms,
allows the input data to be expressed in an even more human-readable
form, and reduces the runtime overhead of the endpoints map by a factor
of 31, all with no loss of functionality, compatibility or flexibility.
Since we don't run a setup script to generate the tarball, the
endpoint_map.yaml output is checked in to source control. The build
script offers a --check option that can be used to make sure that the
output file is up-to-date with the input data.

Our current nova-neutron configuration does not work with
the latest puppet-nova. In particular, this patch[1].
This commit adds keystone v3 endpoints to the map and gets the
nova::network::neutron configuration to use them.

The commit daad3d4224f12d2c23c41a70cdf522e7c55536ba added a bunch of new
endpoints, but failed to use the new input data in calculating the
outputs: the GlanceRegistry ones use the Glance endpoints and the
Horizon one the Heat endpoint. This would cause anything querying these
endpoints from the endpoints map to get the wrong ports.

Right now our vncproxy settings are hard-coded to http and the
non-ssl port. This change adds a vncproxy entry to the endpoint
map and uses those values to configure the proxy correctly on
compute nodes. This is sufficient to get it working in my
environment with ssl enabled.

Integration of OpenStack data processing service (sahara) with
TripleO.
- Deploys sahara in distributed mode (separate api and engine
processes on each controller node)
- Load balancing w/haproxy
- RabbitMQ/MySQL supported per current TripleO standard
- Minimal configurability at this time

This aligns the parameter default values from python-tripleoclient
with tripleo-heat-templates. This is in preparation for removing
all the defaults from the client, and maintaining them only in the
templates.

We need to pass details of the Glance Registry and public Horizon
endpoints to the load balancers so add them to the EndpointMap

CloudName is the DNS name for the public VIP this means we will likely
want it available for use in the endpoint hostnames, rather than people
needing to copy and paste the same hostname

Because many of the service endpoints URLs use the same patterns for
generating the URLs it makes sense to use the same templates to reduce
the copy and paste.
In the process also adds support for explicitly specifying hostnames
for use in the endpoints. Note: DNS must be pre-configured. The
Heat templates do not directly configure DNS.
