features:
- Adds a new "immutable" boolean field to the parameters section in
a HOT template. This gives template authors the ability to mark
template parameters as immutable to restrict updating parameters
which have destructive effects on the application. A value of
True results in the engine rejecting stack-updates that include
changes to that parameter. When not specified in the template,
"immutable" defaults to False to ensure backwards compatibility
with old templates.
