Link replication plugin

After splitting the `replication` plugin into `api` and main modules, we
cannot relay anymore on the `replication` classes being loaded before
`pull-replication` starts therefore we need to embedd those classes
directly into our JAR file by removing `neverlink = 1` from the build
configuration.
