Steve Baker 1733d74392 Set the name property for all deployment resources
There are two reasons the name property should always be set for deployment
resources:
- The name often shows up in logs, files and API calls, the default
  derived name is long and unhelpful
- Sorting by name determines the merge order of os-apply-config, and the
  execution order of puppet/shell scripts (note this is different to
  resource dependency order) so leaving the default name results in an
  undetermined order which could lead to unpredictable deployment of
  configs

This change simply sets the name to the resource name, but a future change
should prepend each name with a run-parts style 2 digit prefix so that the
order is explicitly stated. Documentation for extraconfig needs to clearly
state what prefix is needed to override which merge/execution order.

For existing overcloud stacks, heat currently replaces deployment resources
when the name changes, so this change

Example extra config for cluster config
this example collects the hostname and MAC addresses for each node in
the deployment, then distributes that info to all Controller nodes.
