Pipeline Editor: Show configuration validation status

Summary

Single file editor shows whether the configuration is valid. We need to show the same status on the Pipeline Editor.

In the single file editor we have the following notice that shows the validity of the currently saved file:

Proposal

Show correct configuration status at all times, and adjust it as user types and makes changes to configuration.

Use the same design as currently used in the single file editor, with a couple adjustments:L

• The status needs to be adjusted continuously as changes are made to the configuration. To make the change between valid/invalid status less drastic we can use a subtle fade-out animation to smooth the transition.
• When configuration is valid, remove the "Learn more" link.
• When configuration is invalid, "Learn more" link should be present.

Notes

• This is considered a blocker for our MVC at &4540 (closed)
