change to variable to use '_' underscore rather than '-' dash

[epicanthal]

Referencing the variable 'cisco_ios.config.interface-config' results in "VARIABLE IS NOT DEFINED!: 'config' is undefined"

Tasks:

    - name: PARSE THE RAW OUTPUT
      command_parser:
        file: "{{ parser_template_dir }}/ios/show_run_interface.yaml"
        content: "{{ ansible_net_config }}"

    - debug: var=cisco_ios.config.interface-config.Vlan1
