Allow creating multiple workspaces from the single sample

[akurinnoy]

What does this PR do?

This PR main goal is to allow users to create multiple workspaces from the same sample. To get this I added a new step to the Factory flow that handles workspace names conflict and prompts the user whether to switch to an existing workspace or to proceed to create a new workspace (appending a suffix to its name):

Opening the existing workspace:

Screen.Recording.2022-09-12.at.11.32.37.mov

Creating a new workspace:

Screen.Recording.2022-09-12.at.11.34.14.mov

Additionally, this PR changes a bit the workspace loading flow: it adds a new step to check if the number of simultaneously running workspaces is within the limit:

Screen.Recording.2022-09-12.at.11.36.05.mov

What issues does this PR fix or reference?

fixes eclipse-che/che#21561

Is it tested? How?

1. Try to create multiple workspaces from a single sample (or devfile)
