Rename OSGi classes for Java naming conventions (#9320)

- Rename OSGi to Osgi in class names.
- Rename VaadinOSGiPortlet to OSGiVaadinPortlet for consistency with
Spring, CDI etc. add-ons
- Add missing javadoc

 Vaadin Framework 8.1 and later versions provide two supported ways of publishing static resources for OSGi: by making OSGi services implementing an interface or by explicit calls to a service.
 
-The easiest way to publish a theme or a widgetset is to create a class implementing the interface [interfacename]#OSGiVaadinTheme# or [interfacename]#OSGiVaadinWidgetset# and annotating it with [interfacename]#@Component# to make it an OSGi service. This automatically publishes the theme or the widget set from the bundle at a path that contains the Vaadin Framework version used by the application.

-Alternatively, an OSGi bundle activator or an SCR Component [interfacename]#@Activate# method can obtain an instance of [classname]#VaadinResourceService# from [classname]#OSGiVaadinResources# and explicitly call its methods to publish a theme, a widget set or an individual file in the bundle as a static resource at the correct path.
