Elastic have announced [1] that embedded Elasticsearch is no longer
supported. This commit brings us into line with that announcement by
removing the auto-configuration that would create an Elasticsearch
Node and NodeClient.

To use the Elasticsearch auto-configuration, a user must now provide
the address of one or more cluster nodes
(via the spring.elastisearch.cluster-nodes property) which will then
be used to create a TransportClient.

Previously, RedisTestServer only supported Jedis and would blow up if
only Lettuce was on the classpath. This commit defensively checks which
driver is available and chose the appropriate one, defaulting to Jedis.

  Reduce Lettuce shutdown timeout to 100ms
  Set Lettuce shutdown timeout properly

Closes gh-9526

Reducing the default to 100ms is a good compromise to retain a quiet time
in for parallel execution and optimize for default, single-threaded
execution (such as test execution or regular application shutdown). The
shutdown timeout can be adjusted to fit specific application needs.

See gh-9526

We now properly set the Lettuce client shutdown for unpooled and pooled
configuration.

  Allow abstract serializers/deserializer in @JsonComponent

Closes gh-9443

Previously JsonComponentModule tried to instantiate all
inner classes and failed with InstantiationException when
the class is abstract and extends JsonSerializer/JsonDeserializer.
With this change is now possible to have common logic inner abstract classes.

  Add Slice test annotation for Redis

Closes gh-9224

This commit adds new annotation `@DataRedisTest` which provides test
infrastructure for redis.

See gh-9224

Rather than checking if Jedis is on the classpath, this commit changes
the conditions of `RedisRepositoriesAutoConfiguration` to check for the
presence of a `RedisConnectionFactory` bean that is going to be
necessary to create the Redis repositories anyway.

Checking for Jedis is no longer correct since we now support Lettuce as
well.

  Polish "Use Redis client configuration to configure connection factories"
  Use Redis client configuration to configure connection factories

In particular, the Lettuce code is not using the new builder API when
pooling is required. This will be fixed in a future milestone.

Closes gh-9510

We now use LettuceClientConfiguration and JedisClientConfiguration to
configure connection factories. Client-specific configuration can be
customized by providing LettuceClientConfigurationBuilderCustomizer and
JedisClientConfigurationBuilderCustomizer beans.
