Add visual indicator to scorch to indicate Initial SOH running/pending

[ahasandk]

Scorch allows to start a run as soon as the experiment starts, even if initial SOH has not run yet and throws an error when attempting to run the pipeline. From a UI perspective, it may help to have a visual indicator also so the user doesn't try to run the pipeline before initial SOH checks have completed.

+1, as I ran into the same issue. SoH was still running (for my particular use case it took ~6 minutes to run), but Scorch seemed like it was all good to start. Maybe gray out the button?
