Dashboard factory enhancement

[olexii4]

Is your enhancement related to a problem? Please describe.

In the case with CHE7 workspaces and their devfiles, which can be used instead of factories, I'm always frustrated when I see CHE factories without devfile supporting. On the other hand - we don't have a special UI for using devfiles instead of factories.

For creating a new workspace from the devfile we need to type a special URL(for example 'http://che-che.192.168.99.100.nip.io/f?url=https://raw.githubusercontent.com/eclipse/che/master/dashboard/devfile.yaml') or create any new workspace then change devfile content.

Describe the solution you'd like

I propose the next UI changes:

To have special tabs for creating a new workspace from the existing workspace, local devfile or git resource(include target devfile choosing).

@slemeur WDYT?

@olexii4 isn't it a duplicate of #12925?

[olexii4]

@l0rd It is not a duplicate. It is a purpose to hide factories until they will work with CHE 7 workspaces. And UI purpose which helps us to create a new workspace, based on another CHE7 workspace. Create a new workspace from the devfile(local or remote).

Because I always do it by my hand. It is small changes but very useful for me as a CHE7 developer
