Feat(plugins): Updated convert_dicts filter for list values in dictionary

[Shivani-chourasiya]

Change Summary

Updated convert_dicts filter for list values in dictionary

Related Issue(s)

Some of the data models have list of dictionaries inside nested dictionary, for which we need to introduce a new key in the data model schema and templates of eos_cli_config_gen_v4.0 , which is affecting molecule execution of older templates(eos_cli_config_gen) as the key is not found.
Example:
OLD

ip_extcommunity_lists:
  TEST1:
      - type: permit
        extcommunities: "65000:65000"
      - type: deny
        extcommunities: "65002:65002"
  TEST2:
      - type: deny
        extcommunities: "65001:65001"

NEW

ip_extcommunity_lists:
  - name: TEST1
    types:
      - type: permit
        extcommunities: "65000:65000"
      - type: deny
        extcommunities: "65002:65002"
  - name: TEST2
    types:
      - type: deny
        extcommunities: "65001:65001"

Component(s) name

arista.avd.convert_dicts

Proposed changes

Checks if the nested dictionary value is list, a new key (secondary_key) will be inserted in the inner dictionary.

How to test

The update to ip_extcommunity_lists.yml in this PR will fail with the older code.
