We now support HSTRLEN command throug RedisHashCommands for Lettuce and Jedis in both an imperative and reactive manner.
However, Jedis not natively supporting HSTRLEN via its API we’ve come up with some more reflective invocation allowing to execute commands currently not known by Jedis. We also added this behavior to the cluster implementation which as of now also supports RedisClusterConnection#execute.

Change return type for mset from void to Boolean. Add missing Nullable annotations. Add Javadoc.
Disable flakey tests for now.

We now use a fallback exception translation strategy in JedisClusterConnection to map all non-mapped exceptions to RedisSystemException. This change prevents null pointer exceptions caused by potentially throwing null.

Add NonNullFields to packages. Add missing Nullable annotations. Extend Javadoc. Replace simple equals/hashCode methods using Lomboks EqualsAndHashCode annotation. Use RequiredArgsConstructor for private classes in favor of own constructors. Replace null-checks with qualified access whether objects are empty/applicable. Rearrange methods according to interface ordering.
Remove demo code from KeyspaceConfiguration.

Mark all packages with Spring Frameworks @NonNullApi. Add Spring's @Nullable to methods, parameters and fields that take or produce null values. Adapted using code to make sure the IDE can evaluate the null flow properly. Fix Javadoc in places where an invalid null handling policy was advertised. Strengthened null requirements for types that expose null-instances.
Resolve some of the inherited null invariants, align Converters to null contract.

Remove final keywords from variables in ClusterCommandExecutor. Reduce constructor visibility of driver-specific commands classes. Fix Javadoc.

We removed the geo prefix from the imperative and reactive GeoOperations interfaces and our methods to match a more expressive scheme:
geoAdd(…) -> add(…)
geoDist(…) -> distance(…)
geoHash(…) -> hash(…)
geoPos(…) -> position(…)
geoRadius(…) -> radius(…)
geoRadiusByMember(…) -> radius(…)
geoRemove(…) -> remove(…)
Methods on the imperative API remain as deprecated default methods to retain compatibility and not enforce changes in the client code.

We now release Jedis cluster node connections with Jedis.close() to the pool instead of Pool.returnResource(…). The close() method itself checks whether the connection was broken and if so, the connection gets destroyed. Destroying broken connections prevents the pool from supplying broken connections on borrow when testOnBorrow is disabled.
The only case where we return broken resources ourselves to the Pool is when we discover a broken connection ourselves: If we run into a NullPointerException or RedisConnectionFailureException, then we consider a connection is broken.

Remove builder interfaces and aim for classes instead.
Also use delegation for builders avoiding constructors with too many arguments.
Alter ConnectionProvider#getConnection(Class) to return a typed connection as this is is the expected return type given the input parameters used.
Remove LettuceConnectionProvider.getConnection() method as it makes no longer sense for the non-lambda enabled interface. Remove unnecessary casts.
Add connection factory to cleanup-tracker on test class instantiation instead within the parameter supplier method to prevent shutdown by other cleanup calls that may happen in between. Reuse client resources.

We now support Lettuce connection pooling by configuring a specialized client configuration via LettucePoolingClientConfiguration.builder(). Pooling settings can be configured through the builder and used with LettuceConnectionFactory.
Connection pooling is supported with Standalone and Sentinel-managed connections.
LettucePoolingClientConfiguration.builder()
.poolConfig(poolConfig)
.and() // allows configuration of further settings.

We now create and release Lettuce connections using LettuceConnectionProvider. Connection providers encapsulate the underlying client and expose only creation and release methods. A connection provider can provide connections for Standalone or Cluster connections or wrap a LettucePool.
Previously we used RedisClient and RedisClusterClient directly which required context propagation (pooling/non-pooling) conditional code to obtain the appropriate connection type.
Original Pull Request: #262
We now request a cluster node connection directly from the driver's connection handler and initiate reconfiguration if a cluster node is known through the topology but has no connection pool yet. This can happen if a cluster node is added to the cluster after the connection was initialized.
The connection handler cannot be obtained directly although the field where it's held is protected which increases the amount of necessary test code and reflection access to the connection handler.
Jedis discovers nodes during startup, on demand (full scan) or when requested (e.g. by a cluster redirection).

Rename *Operators -> *Executor and use plain RedisElementReader/Writer instead of SerilaizationPairs. Therefore we’ve introduced new static factory methods creating the required Reader/Writer from a given RedisSerializer.
Additionally some minor Javadoc updates, tests and removal of redundant null checks.

We now support Redis Lua script execution using reactive infrastructure through the reactive connection and template API.
Flux<V> execute = reactiveTemplate.execute(new DefaultRedisScript<>("return redis.call('get', KEYS[1])", String.class), Collections.singletonList(key));
Release the reactive connection consistently after Publisher termination. Extract shared code between DefaultScriptExecutor and DefaultScriptOperators in ScriptUtils.

Rename JedisConverters.zAddArgsConvertor(…) to toTupleMap(…) and reorder method to group with other tuple conversion methods. Add author tags.
Create tests for zadd with tuple using Redis Cluster. Enable pipelining and transactions for zadd using Jedis. Adopt tests.
