Make Ceilometer more configurable.

In order for compute to work with HA controller setup, we need to:
- Make Ceilometer optional
- Provide the keystone auth url for ceilometer to use.
Fixes for Heat and Horizon.

- Heat puppet module has been updated, which means we need to split out
  call to heat::keystone::auth to also call heat::keystone::auth_cfn.
- Horizon needed to be set to top scope call since we now have a
  quickstack::horizon class.

Never create a cloned resource unless it is available on all nodes.
More Fixes for Heat.

  - Add auth_encryption_key which is now required.
  - sql_connection string moved to ::heat since ::heat::db no longer
    exists.

Swift only has public VIP, make Keystone reflect that

This was the cause of the almost impossible to track "value is a
required option for Puppet::Parser::Resource::Param" error. We're
trying to use map_params on params that don't exist. From reading
previous code it seems that private/admin VIPs for Swift are not
present on purpose (e.g. Swift load balancer also expects only public
VIP), so i'm fixing it by using public VIP for all endpoints instead
of introducing new VIPs.
Add *_network params and logic.

The purpose of this is to allow a user to specify what they know, which
sometimes is not the nic (which may not be known to them at setup time until
after the machine is provisioned).  They should be able to provide the network
they know a nic should be in though, and we can use this to figure out which nic
got attached to that network.
