odo should also provide the way to get information about available preferences and preference types.
Upstream issue https://github.com/openshift/odo/issues/3094.

First implementation can be based on static list based on what -h command prints out.

Start by tracing how the VS Code extension exposes odo commands and views, then compare that entry point with the preference names and types listed in the issue. The work is done when users can view the available odo preferences and their types and set the supported values through the new view.
