Review Comment:
I followed @dstandish 's recommendation on removing the dependency on
Pandas. I'm sorry, I hadn't realised it wasn't a core Airflow dependency!
I also implemented @potiuk's suggestion on capturing the `ValueError`
exception instead of the `empty` suggestion. There were two motivations for
this:
1. Assuming `_do_render_template_fields` receives a non-empty `Pandas`
`DataFrame`. Does Airflow have the capability of rendering Jinja in DataFrames?
Wouldn't it make more sense to `continue`?
2. It feels more resilient since it works with classes which do not
implement the `empty` method.
