DATAREDIS-574 - Introduce dedicated RedisClientConfig

[mp911de]

Add JedisClientConfiguration and LettuceClientConfiguration to abstract client-specific features with their configuration options. Client configurations are built with a builder that create immutable instances. Client configurations replace property storage within a RedisConnectionFactory. A RedisConnectionFactory created without a client configuration uses a mutable client configuration.

Lettuce:

LettuceClientConfiguration configuration = LettuceClientConfiguration.builder()	.useSsl()	.verifyPeer()	.startTls().and()	.clientOptions(clientOptions)	.clientResources(sharedClientResources)	.timeout(Duration.ofSeconds(10))	.shutdownTimeout(Duration.ZERO)	.build(); LettuceConnectionFactory connectionFactory = new LettuceConnectionFactory(	new RedisStandaloneConfiguration(),	configuration); 

Jedis:

JedisClientConfiguration configuration = JedisClientConfiguration.builder()	.useSsl()	.hostnameVerifier(new MyHostnameVerifier())	.sslParameters(sslParameters)	.sslSocketFactory(socketFactory).and()	.clientName("my-client")	.connectTimeout(Duration.ofSeconds(10))	.readTimeout(Duration.ofSeconds(5))	.usePooling().poolConfig(poolConfig)	.build(); JedisConnectionFactory connectionFactory = new JedisConnectionFactory(	new RedisStandaloneConfiguration(),	configuration); 

Add RedisStandaloneConfiguration to be consistent with RedisSentinelConfiguration and RedisClusterConfiguration and extend environmental configuration with password and database (Standalone and Sentinel).

Remove system properties defined for surefire because they are not used and javax.net.ssl.keyStore causes exceptions when obtaining the default SSL context.
