Describe the solution you'd like

After this recent PR, when the attribute controller.devfile.io/bootstrap-devworkspace: true is set on a DevWorkspace object, then the project clone is configured to search for a devfile and apply it after cloning the DW projects.

To close the issue to automatically restart a workspace and the epic to support resolving devfiles for any git service we need now to automatically add this attribute when the che-server fails to resolve a Devfile (because of an unsupported git service or because an error occurred).

@l0rd am I correct that this issue boils down to setting attribute when we start workspace with default devfile

[l0rd]

In theory, when che-server is able to connect to the git service API and figures out that there is no devfile at the root of the repository, project-clone container should avoid inspecting again for the same devfile. In practice I don't think that's a big deal if both (che-server and project-clone) look for the devfile.

Another more important case is when the user explicitly click on "start using the default devfile". In this case we don't want to set controller.devfile.io/bootstrap-devworkspace: true.

@l0rd in this cases, there is a question if we need an extra UI item, clicking on which the label would be added. If we want to implement it without UI changes, it is not clear when restart with default devfile should be shown in general

[l0rd]

@ibuziuk, UI item? No, there should be no need.

What I mean is that if the startup of a workspace fails because of an invalid devfile, we currently prompt the user to restart with default devfile. But if the default devfile has controller.devfile.io/bootstrap-devworkspace: true then, the project-clone container will find the invalid devfile in the git repository and replace the default devfile with it...
