Osgi bundles

[badfish69]

Update packaging to generate OSGI manifest data, to better support deployment in OSGI environments.

Sorry - take #2 on this pull request, there was a missing commit.

The first commit is simple enough, it just uses the maven-bundle-plugin to add the OSGI headers to the manifest of each jar file.

The second commit is more of a breaking change. OSGI does not like multiple bundles (jar files) providing classes from the same package namespace. In this case, you're using the same namespace for the odata-client-msgraph and odata-client-msgraph-client-builder packages (com.github.davidmoten.msgraph). I've moved the builder classes into their own namespace, but this might have implications for client code if people have used any of the builder classes directly.
