Create the MVP for Config Plan Post Processing

[jeffkala]

Environment

• Nautobot version:
• nautobot-golden-config version:

Proposed Functionality

1. Config plan detail view offers a on demand rendering so proper approval of the config-plan can be acheived.
2. Deployment via job button and regular job should have a post processing rendering step before the configs are pushed to the devices.
3. Not post processing configs should be logged anywhere.
4. post processing in the config plan detail view must be done using the existing framework and done in memory.

Use Case

Using config deployments to rotate credentials in a safe way.
