[Suggestion] It would be better to remove the containerized function app when executing containerized function app unsupported commands

[v-ruizh]

OS: All
Build Version: v1.15.1-alpha.0
Regression: Not a Regression

Repro Steps:

1. Create a containerized function app.
2. F1 -> Select "Azure Functions: Configure Deployment Source...".
3. Check whether containerized function app shows in the function app list.

Actual:
The containerized function app shows in the function app list.

Suggestion:
It would be better to remove the containerized function app when executing containerized function app unsupported commands.

More Info:

1. Fail to execute "Configure Deployment Source..." command for a containerized function app.
   
2. This bug also reproduces when executing other containerized function app unsupported commands, such as "Start/Stop Streaming Logs", "Start/Restart/Stop", "Deploy to Slot"...

Hello! Thanks for filing this issue. Even though the containerized function app does show in the quick pick when a containerized function app is chosen for these unsupported commands an error like this should show up:

Please let me know if that is not the case!

Yes, I added the more info in the bug. There is an error when executing the unsupported commands for containerized function app. I saw you have fixed the same issue for Deploy commands, so log a new bug for other commands.

Is this by design for other unsupported commands?
