Boden R c2756c3d98 Formalize base service classes ... The PluginInterface and WorkerSupportServiceMixin classes were rehomed to neutron-lib recently [1] and included a private version of the respective classes. Based on the existing usages of such [2][3], this patch: - Renames WorkerSupportServiceMixin as WorkerBase making it public for consumption [2]. - Collapses _PluginInterface into ServicePluginBase making the definition more compact and understandable. - Formalizes the use of ServicePluginBase by updating the docstring in ExtensionDescriptor to indicate an instance of ServicePluginBase is used for plugin interfaces. This is kosher as existing uses today all return extension plugin interfaces that are subclasses of ServicePluginBase and not PluginInterface. Also see related neutron consumption patch [4].
