Jinja templating for config file formats

[danielabdi-noaa]

Description

Currently config files support jinja templating using extend_yaml function that fills values of templated jinja2 entries refering to variables in the same config file. However, support for jinja templating of a block of yaml entries is not supported. This may come in handy, for example, when you want to define a set of variables only if a certain condition is met. With the existing approach, one has to define the variables and set to null/empty even when they are not needed.

Solution

Add jinja templating to all config file formats: yaml, json, xml, ini, and shell

Requirements**

None

Acceptance Criteria (Definition of Done)

Fundamental tests pass
