Inconsistent use of parameter_defaults in environment files

[Jiří Stránský]

In the environments/ subdirectory of tripleo-heat-templates, we mostly use parameter_defaults, but some of the environment files still use parameters. This can lead to confusing behavior with respect to parameter priority when passing environment files to deploy/update commands. Users might expect that subsequent environment files take priority over preceding ones, but that might not be the case if the preceding environment files use `parameters`, while the subsequent ones use `parameter_defaults`.

I've started fixing these as part of the composable services stuff as well (because it is a requirement for me).

    Always use parameter_defaults in environment files

    In the environments/ subdirectory of tripleo-heat-templates, we mostly
    use parameter_defaults, but some of the environment files still use
    parameters. This can lead to confusing behavior with respect to
    parameter priority when passing environment files to deploy/update
    commands. Users might expect that subsequent environment files take
    priority over preceding ones, but that might not be the case if the
    preceding environment files use `parameters`, while the subsequent ones
    use `parameter_defaults`.

    This commit switches all `parameters:` uses in environments/
    subdirectory to `parameter_defaults:`.
