[AIRFLOW-1076] Add get method for template variable accessor (#6793)
Support getting variables in templates by string. This is necessary when
fetching variables with characters not allowed in a class attribute
name. We can then also support returning default values when a variable does
not exist.

> Project: Apache Airflow

> Priority: Minor
> Fix For: 1.10.7
>
>
> Currently, one can fetch variables in templates with {{ var.value.foo }}. But
> that doesn't work if the variable key has a character you can't use as an
> attribute, like ":" or "-".
> Should provide alternative method of {{ var.value.get('foo:bar') }}. Can then
> also supply a default value if the variable is not found. This also allows
> you to fetch the variable specified in another jinja variable (probably not
> common use case).
