Fixed cluster connection detmination function.

Due to the refactor for the cluster manager/connection manager system to
use otp behaviors, the raw message method of getting stats has been ousted.
Instead, it uses a call. To allow the riak_test to be able to check older
clusters as well as the method, the function was extended to try new and
then the old.

Don't wait for convergence of the ring, because bucket properties are no

which means the gossip has stabilized.
