Make WorkBench status message less ambigous

Regarding WorkBench status message when you click on Validate/Upload/Unupload:

As to the "Beginning the Validating..." message, currently, it can mean at least 3 things and there is no way for the front end to differentiate between them:
The upload worker is preparing to validate the DS and validation should begin soon
The upload worker is currently busy with another DS and validation would not begin until that DS is validated
The upload worker is down or not responding. The validation would not begin and the "Beginning the Validating" would stay up forever
All of this also applies to Upload and Rollback.

Maybe front-end can say something after 30seconds, or maybe a way to detect if the worker process is busy should be added

From @grantfitzsimmons:

Currently the WorkBench just hangs on the validation or upload function if the worker process is not running.

It would be nice to have some icon and tooltip (or something similar) that displays a warning if it pings the server and the worker is not running. Even if it is busy, it is helpful to have some indication.

There have been many instances where users ask [email protected] for help due to this process not running. Without an indication for a user, it seems that the WorkBench is just always busy, even when it is definitely not the case.

Importantly, there should be a way to warn the user that the worker is not running when when using the WorkBench in a visual way! Most important part of my issue 😉
