@param payload: String of jinja template content. Should begin with
## template: jinja
.
@param payload_fn: String representing the filename from which the payload
was read used in error reporting. Generally in part-handling this is
'part-##'.
@param instance_data_file: A path to a json file containing variables that
will be used as jinja template variables.
@return: A string of jinja-rendered content with the jinja header removed.
Returns None on error.

Provide underscore-delimited key aliases to simplify dot-notation
attribute references for keys which contain operators "." or "-".
This provides for simpler short-hand jinja attribute notation
allowing one to avoid quoting keys which contain operators.
{{ ds.v1_0.config.user_network_config }} instead of
{{ ds['v1.0'].config["user.network-config"] }}.
:param orig_name: String representing a jinja variable name to scrub/alias.
:return: A string with any jinja operators replaced if needed. Otherwise,
none if no alias required.
