We now allow configuration of the execution profile and serial consistency through QueryOptions and CassandraAccessor/ReactiveCqlTemplate. Settings are applied on a per-Statement basis. The newly ExecutionProfileResolver can resolve the profile either from a profile name or a DriverExecutionProfile object for more flexibility.
With this change, we removed the support for setting a RetryPolicy directly as the new driver 4 does not support a direct configuration of the RetryPolicy. Instead, the RetryPolicy is configured through an execution profile.
