Telemetry Plugin support in DevWorkspaces (workspaces started with the DevWorkspace engine)

Is your task related to a problem? Please describe.

As part of this task, we need to make sure that the telemetry plugin that is possible to enable for Che 7 workspaces can be re-used, or need to be adapted, for the DevWorkspaces - https://www.eclipse.org/che/docs/che-7/extensions/telemetry/

Describe the solution you’d like

It should be possible to enable telemetry plugin for all DevWorkspaces running on a cluster. Currently, in Che 7 plugin the can be enabled via

spec:
  server:
    customCheProperties:
      CHE_WORKSPACE_DEVFILE_DEFAULT__EDITOR_PLUGINS: 'eclipse/che-machine-exec-plugin/7.32.0,https://your-web-server/meta.yaml'

Describe alternatives you’ve considered

N/A

Additional context

telemetry - https://www.eclipse.org/che/docs/che-7/extensions/telemetry/ Devfile v2 and IDE plug-ins - https://che.eclipseprojects.io/2021/06/23/@florent.benoit-devfile-v2-and-ide-plug-ins.html

@ibuziuk I am ok with this approach but consider a couple of things:

1. devWorkspace section in the CRD should disappear because everything will be devWorkspace
2. The default plugins will depend on the editor, so maybe it would be better to specify the editor too

So maybe something like this may be better:

  server:
    workspacesDefaultPlugins:
      - editor: 'che-theia'
        plugins: ['github/vscode-pull-request-github/latest', ...]
      - editor: 'vscode'
        plugins: ...

For managing default plugin templates, we can do what the Web Terminal Operator does in order to avoid maintaining DWTs across the cluster. If we create DevWorkspaceTemplates in a known namespace (WTO uses its current namespace) and add the annotation

controller.devfile.io/allow-import-from: "*"

then these DWTs can be used in any workspace on the cluster via

spec:
  template:
    components:
      - name: my-default-plugin
        plugin:
          kubernetes:
            name: k8s-dwt-object-name
            namespace: k8s-dwt-namespace
