Support telemetry for Red Hat VS Code extensions in Eclipse Che

Is your task related to a problem? Please describe.

In order to enable telemetry support in Che, we need to add the vscode-commons vsix to all Che plugins in the plugin registry.

Describe the solution you’d like

Since all plugins in the registry should have this vsix in their extensions list, it’s something we can add at build time. Perhaps something like:

• Create a defaultExtensions.json in the root of the plugin registry. This file will contain a list of vsix files that should be present in all Che plugin registry entries
• Modify the che-plugin-registry build process to automatically append any vsix listed in defaultExtensions.json to the extensions field of every generated meta.yaml file

Describe alternatives you’ve considered

Manual addition of the vscode-commons vsix file to all Che plugin entries in che-theia-plugins.yaml

Additional context

Openshift connector has removed the dependency to vscode-commons https://github.com/redhat-developer/vscode-openshift-tools/commit/f22a6d3308ad4bd6dbf43665050d3a9c453b7083 but it has not yet released a new version but I would say it’ll be done pretty soon.

I think that if we include commons extension in the openshift connector, it will collide with the plugin added by default by che-server (so should be removed first)
