Description of problem:

When implementing the console.create-project-modal extension point for CreateProjectModal, the implemented solution was to replacie the content of the modal. As it occurs this solution has its issues, cause if multiple plugins use this extension, only one of the plugins will actually be able to use and override this modal.

We need to evaluate if this solution can be fixed. Rather then overriding the modal a plugin would add an additional section/tab and make it a wizard, or if there is a different suitable solution.

Currently console itself is using the extension so if a plugin or multiple plugins will use it as well, there will be a conflict and only one of them will get rendered in the modal.

PR: https://github.com/openshift/console/pull/13825/files

Version-Release number of selected component (if applicable):

    4.17

How reproducible:

    Always

Steps to Reproduce:

    1. Update two plugins to use the console.create-project-modal extension       
    2. Deploy and enable these plugin on the cluster
    3. Check the CreateProject modal
    

Actual results:

    Only one of these plugins will get to use the extension and its code will get rendered in the modal. No error or warning is surfaced to the user.

Expected results:

    Code of all the plugins, which use the extension should be render in the modal.
