Goal

Allow users to revert a configuration applied through an NNCP.

User Stories

• As a Console user, I expect to have a "delete" option available on the NodeNetworkConfigurationPolicies I created.
• High-Level goal-based user story, with context.
  "As a <VM Owner/Cluster Admin>, I want <to Achieve Some Goal>, so that <Some Reason/Context>."
• another user story

Non-Requirements

• List of things not included in this epic, to alleviate any doubt raised during the grooming process.

Notes

• This could be using `nmstate revert`
• Investigate whether setting "absent" on everything is good enough or if it is insufficient.
• The revert does not have to cover 100% of situations, but we should be able to define a clear set of scenarios where it is useful.
