Add dependentProjects to the Devfile/DevWorkspace spec

Add field 'dependentProjects' to the devfile API. Dependent projects
are additional projects that are related to the 'main' project in a
Devfile, allowing a devfile to specify e.g. dependencies or related
projects that are useful in development.
