Really use Cassandra Storage in HTTP Acceptance tests (#1416)

* Use CassandraStorage not MemoryStorage for http acceptance tests.
* Bump management API client version.
* Switch more JMX references to reflect that it could also be HTTP in ClusterFacade.
* Comment out test steps which rely on getPendingCompactions.
* Comment out percent-repaired related test.
