Rerun network setup on deployed nodes
This is required to apply changes that could be made to the networking configuration of environment.
The major case is: add/remove node network group(s).

The configuration changes are not tracked as nailgun does not have proper functionality for that.

New key is introduced in task description: reexecute_on (list). Deployment tasks which are to be re-executed on deploy changes must have

reexecute_on:
    - deploy_changes
