title: MulePollManager has disappeared from MUnit 1.0.0
body: <p>We used the class org.mule.munit.MunitPollManager(in the munit-utils package) in older versions of MUnit to make sure that our poller did not start when the flow started, however this seems to have disappeared when Munit migrated to 1.0.0. How can this be replicated in the new Munit?</p>
