Nested validation breaks with ResourceGroup and non-defaulted count parameter

[Steven Hardy]

[stack@instack ~]$ heat template-validate -f rg.yaml --show-nested
ERROR: The Parameter (the_count) was not provided.

[stack@instack ~]$ cat rg.yaml
heat_template_version: 2016-10-14

parameters:
  the_count:
    type: number

resources:

  the_group:
    type: OS::Heat::ResourceGroup
    properties:
      count: {get_param: the_count}
      resource_def:
        type: OS::Heat::RandomString

We're validating the count too eagerly, but I'm not sure what value we can pass (zero?) which will enable the nested validation to work in this case.

    Return nested parameters for resource group.

    This refactors the building of schema from parameter validation to use a
    new method (which doesn't keep stacks in memory), and use that new
    method for providing proper schema for resource group when the size is
    0.
