Add support for ZMSCORE through variadic ZSetOperations.score(K key, Object... o) and ReactiveZSetOperations

[mp911de]

Hi, this is a ideal-for-contribution issue. This means we've worked to make it more legible to folks who don't haven't contributed much to our codebase before.

Problem

Redis 6.2 introduced a new command ZMSCORE as variadic variant of ZSCORE. We want to support this command in Spring Data Redis.

Solution

Add List<Double> score(K key, Object... o) to ZSetOperations and ReactiveZSetOperations. The reactive API should return Mono<List<Double>>. Add a score(Object…) method to BoundZSetOperations and make sure to implement the methods on the classes implementing the interfaces.

Extend the reactive and imperative command interfaces ReactiveZSetCommands respective RedisZSetCommands including DefaultedRedisConnection. You will need to extend JedisClusterZSetCommands, JedisZSetCommands, and LettuceZSetCommands.

AbstractConnectionIntegrationTests is the main test class for connection-related tests.
