Commit ce9c7bbdfcbc931029077f5564e60746dba05cfa in incubator-airflow's branch

[AIRFLOW-2415] Make airflow DAG templating render numbers
Currently, if you have an operator with a template
fields argument, that is a dictionary, e.g.:
template_fields = ([dict_args])
And you populate that dictionary with a field that
an integer in a DAG, e.g.:
...
dict_args = {'ds': '{{ ds }}', num_times: 5}
...
Then ariflow will give you the following error:
{base_task_runner.py:95} INFO - Subtask:
airflow.exceptions.AirflowException: Type '<type
'int'>' used for parameter 'dict_args[num_times]'
is not supported for templating
This fix aims to resolves that issue by
immediately resolving numbers without attempting
to template them
Closes #3410 from
ArgentFalcon/support_numeric_template_fields
> Airflow Operators are unable to support integers in templatized fields
