/**
* This Activator implements the required glue between an OSGi Repository implementation and the
* OSGi CT. It is needed to prime the repository with the data needed by the CT and works as
* follows:
* <ul>
* <li>The CT registers a String service with as property {@code repository-xml}. This service is
* literally the repository XML needed by the test, and must be fed to the repository implementation.
* <li>When that's done this glue code registers another service with as property
* {@code repository-populated} to signal to the CT that the priming is done.
* </ul>
