Original pull request: #375.
We now shuffle the set of Redis Cluster nodes before retrieving the topology. This change reduces load on the first node in the known nodes set.

Create unit tests for RedisAtomic counter initialization. Refactor setIfAbsent(…) method to initializeIfAbsent() to not expose additional API methods.
Original pull request: #367.
We now use setIfAbsent to initialize RedisAtomic counters if no initial value was given. Using setIfAbsent turns the initialization into a single atomic step that prevents race conditions of the previously check and set method that required two Redis commands.
Previously, concurrent processes (threads, external changes to Redis) could set the initial value between the existence check and the value set operation that caused the last participant to win.

Refactor lower/upper bound retrieval into LettuceConverters for a consistent lower/upper boundary return value. Use minus one (-1) as the upper bound index to always retrieve the last element if the upper boundary is not bounded.
Original pull request: #353.
We now return in List, String, and ZSet commands a lower/upper bound range index to prevent NullPointerException. Previously, unbounded ranges could render null values that were attempted to cast to primitives.
Original pull request: #353.
We now consider a transactional rollback that returns an empty EXEC result as rollback for the CAS (compare-and-set) operation. Previously, we checked only that the response of EXEC is not null. A rollback returns an empty list which was previously considered a successful CAS operation.
The code for CAS is now extracted to CompareAndSet and is reused from RedisAtomic implementations.
