Split org.osgi.test.assertj into org.osgi.test.assertj.framework and org.osgi.test.assertj.promise

[bjhargrave]

Having PromiseAssert in the bundle means all users must provide the promise/function packages. This is unfortunate in the OSGi compliance tests for those test which are not otherwise touching promise.

Since we may make more custom assertj asserts for other packages, we should probably have a unique artifacts for each package.

One bundle per bundle or one per package?

Two artfacts: org.osgi.test.assertj.framework and org.osgi.test.assertj.promise for now.

If we do, for example, custom assertions for ConfigurationAdmin, we would then create a new artifact for that: org.osgi.test.assertj.cm.
