{@code ForwardingAdmin} is the default value of {@code forwarding.admin.class} in MirrorMaker.
Users who wish to customize the MirrorMaker behaviour for the creation of topics and access control lists can extend this
class without needing to provide a whole implementation of {@code Admin}.
The class must have a constructor with signature {@code (Map<String, Object> config)} for configuring
a decorated {@link KafkaAdminClient} and any other clients needed for external resource management.
