[WIP] added commit-confirm options to vyos_config

[lucaelin]

SUMMARY

I've added an option to the vyos_config module to use commit-confirm with a given timeout instead of running a straight commit. This functionality is included in vyos and now exposed to the vyos_config module. If no confirmation is received by vyos, it will reboot into the previously existing config, as an attempt to restore functionality.

The module can also automatically confirm the configuration if the connection remains working after applying the new config, or not confirm the configuration for you, leaving it up to the user to allow further testing and manual confirmation.

COMPONENT NAME

commit-confirm

ADDITIONAL INFORMATION

If you accidentally remove the interface configuration your playbook is using to connect to the router, you would previously get a timeout from the module, but the broken config would still remain on the device. This change allows you to specify a timeout, after which the router reboots into the old configuration.

- name: render a Jinja2 template onto the VyOS router
  vyos.vyos.vyos_config:
    src: "../files/{{ template }}.j2"
    match: smart
    save: yes
    confirm: automatic

- name: render a Jinja2 template onto the VyOS router and test it for one minute
  vyos.vyos.vyos_config:
    src: "../files/{{ template }}.j2"
    match: smart
    save: yes
    confirm: manual
    confirm_timeout: 1

- name: check connectivity
  vyos.vyos.vyos_ping:
    dest: 1.1.1.1
    
- name: confirm configuration
  vyos.vyos.vyos_command:
    commands: 
      - configure
      - confirm
      - exit

I think tests should be implemented for this feature, but I am not sure how. Can you point me in the right directions here please?
