"Rerun" button for dynamic pipeline failures

[Radu Cristescu]

When a dynamic pipeline crashes and doesn't return a reply - or it returns an incorrect reply, there's no way to rerun the pipeline in some cases.

Case 1:

* Normal branch or tag pipeline: Run the pipeline manually using the "Run pipeline" button, selecting the corresponding options.

Case 2:

* Pull Request: there's no way to rerun the pipeline manually. A dummy code push is necessary.
