We're currently keeping the clusters separate at Pantheon Systems
because our core API (which runs on standard Cassandra) is often ready
for the next Cassandra version at a different time than Solandra.
Solandra recently gained dual 0.7/0.8 support, but we're still opting to
use the version on Cassandra that Solandra is primarily being built and
tested on (which is currently 0.8).
