Goal:

Introduce new flags to os-net-config to help with a number of scenarios:

• current-config
  • be able to remove interfaces without using the overliy disruptive --cleanup option
  • pass os-net the existing conifguraiton file as well as the new one so that a delta may be calculated and applied accordingly
• rollback
  • in the event of failure to apply the network, revert back to the previous configuration
• no-abort
  • current behavior is that if one entity is failed, the flow is aborted mid operation, this may result in loss of connectivity
  • with --no-abort (name pending), continue to try and apply the rest of the conifgurtion, even if one entity fails, os-net-config should exit with a specail return code in this case
• detect ip duplicates on --noop
  • even on dry run try to see if there is an ip duplicate (90% of failed config applies are caused by this)
  • consider broadcasting an arp, but verify we dont detect our own address, if already present

Acceptance Criteria:

• the new flags shall be supported for all provider options
•
