With I57047682cfa82ba6ca4affff54fab5216e9ba51c Heat has added
a new template version for wallaby. This would allow us to use
2-argument variant of the ``if`` function that would allow for
e.g. conditional definition of resource properties and help
cleanup templates. If only two arguments are passed to ``if``
function, the entire enclosing item is removed when the condition
is false.

Add a script that does a best effort conversion of
a heat network-config tempalte to an ansible j2
network-config template.
The script uses a networks data file as input to
genereta a map of Heat Parameters to ansible vars.
For parameters not in the generated map the stack
environment is used, parameter values from the
stack environment is hard-coded in the j2 template.
A j2 comment is added whenever a value was hard coded,
in a header comment and also an inline comment if
possible.
NOTE: The j2 reference files in the unit tests was
created by converting heat templates.
