No UI indicator presented to end user after clicking "Pull from Mainframe"

[traeok]

Describe the bug

There is no indication that the "Pull from Mainframe" action is ongoing once a user clicks it. We should show some sort of indication, such as a status bar indicator, to keep end users up to date.

To Reproduce

1. Search for a data set
2. Right-click on a data set member -> "Pull from Mainframe"
3. Notice that no UI indicator appears.

Expected behavior

Users should see some indication that we are actively pulling data from the mainframe.

Hi @t1m0thyj, can you please assign me this issue ? I'd love to work on it !

[t1m0thyj]

@Ash-2k3 Sure, I have assigned you the issue since it has not been worked on for 6 months, feel free to work on it 🙂

Thanks @t1m0thyj, I have started working on it and I began with setting things up in my local machine, I am facing trouble with populating dummy data sets. I tried following this wiki https://github.com/zowe/zowe-explorer-vscode/wiki/Developer-Setup#test-profile-data. But it didn't really help me. I'd appreciate any help on this, Thanks!

[t1m0thyj]

@Ash-2k3 Currently the testProfileData is unused and the only integration tests we actively maintain are for Theia: https://github.com/zowe/zowe-explorer-vscode/wiki/Developer-Setup#run-zowe-explorer-regression-tests-for-theia

If you have made a fix locally and verified that unit tests are passing, then feel free to open a PR 🙂

[Ash-2k3]

@t1m0thyj In that case, I think the wiki should be updated :). Anyways, I have opened a PR for this, but I am a bit skeptical about my approach since I couldn't really test my changes and also because I am new to this codebase, so I am not really used to coding pattern. But I do plan to get used to it overtime 😀. Thanks!

And also is there any issue which you would suggest me to work on after PR of this one gets merged ?
