feat: Retry (rerun) successful workflows from certain steps

[or-shachar]

Summary

• On feat: Allow step restart on workflow retry. Closes #2334 #2431 we added the option to rerun successful steps in the Retry operation.
• This Allowed the user to select which steps to reset as part of the Retry command.
• I think we can use the restartSuccesful property that was added to allow rerunning successful workflow from given steps.

Use Cases

• I created a mechanism for rerun with debug pause (in short: all templates have the env variable ARGO_DEBUG_PAUSE_{{workflow.parameters.pause}}, the default value for pause is NEVER, when I use the Retry I override the value to AFTER).
• I want to be able to use it also for successful workflows (for instance: I need to do manual operation on terraform state, I need to test out something manually etc etc).

Implmentation

The Retry operation will fail if workflow is not in Failed or Error state:

argo-workflows/workflow/util/util.go

Line 806 in ec85683

case wfv1.WorkflowFailed, wfv1.WorkflowError:

IIUC, it should be fairly simple to change this condition to allow other states, in case the restartSuccesful and node selector were given.

WDYT?
