Heat now supports release name aliases, so we can replace the inconsistent mix of date related versions with one consistent version that aligns with the supported version of heat for this t-h-t branch. This should also help new users who sometimes copy/paste old templates and discover intrinsic functions in the t-h-t docs don't work because their template version is too old.

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.

# Parameters passed from the parent template - note if you maintain
|
|
# out-of-tree templates they may require additional parameters if the
|
|
# in-tree templates add a new role.

parameters:
|
|
servers:
|
|
type: json
|
|
# Note extra parameters can be defined, then passed data via the
|
|
# environment parameter_defaults, without modifying the parent template
