New Behavior

The nb_inventory inventory plugin's query_filters, device_query_filters, and query_filters options allow Jinja2 templates.

Contrast to Current Behavior

An example of option query_filters. Jinja2 Templates like the following are not available previously.

query_filters:
  - site: "{{ 'TEST-SITE' | lower }}"

This PR allows Jinja2 template and extra vars.

# ansible-playbook -i test_nb_inventory.yml -e e_site=test-site
...omitted...
query_filters:
  - site: "{{ e_site }}"   # using extra vars
...omitted...

Discussion: Benefits and Drawbacks

We can filter dynamically by specifying filter with extra vars. This can be expected to improve performance compared to retrieving the entire inventory and executing the playbook by specifying the group.

It is backwards-compatible. Strings that do not use Jinja2 templates are interpreted as normal strings.

I fixed conditional expression from 3.1 to 3.2 in tests/integration/targets/inventory-v3.2/runme.sh.
https://github.com/netbox-community/ansible_modules/pull/834/files#diff-da941c534001dc681682cf1403cf1230c459525f75a5914b8cfbf883f47a18a5

Should I have left it as 3.1?
Sorry, I still don't fully understand how testing works.
