fixes the "RetryOnRenew" lease-renewal needed bug in jclouds, locally, with some guice magic

https://issues.apache.org/jira/browse/JCLOUDS-615 / https://issues.apache.org/jira/browse/BROOKLYN-6

when the former above is fixed properly upstream we can undo this.
Nice testing!
Should this be a `Live` test rather than an `Integration` test though?
