Add indication of something happening in Upload/Download local actions

[JillieBeanSim]

Is your feature request related to a problem? Please describe.

I have noticed that some upload/download actions do not have a indicator for action happening. The upload to MVS from local does have a pop up message with cancel button but upload to USS doesn't have that or even a tree indicator of action happening. The same is for download of spool files to local, no indicator for users.

Describe the solution you'd like

It would be nice to have an indicator of some sort, I know we like to keep things in sync with the instance of the MVS tree upload. I think that is fine with a list using multi-select, but for single file in all tree I propose just a simple tree indicator of action happening using the withProgress.
