Add support for XCLAIM in StreamOperations

[zielarz25]

XCLAIM operation was implemented in https://jira.spring.io/browse/DATAREDIS-1084 as a part of RedisStreamCommands, however is not accessible in StreamOperations (rel: #1688) what forces users to use complex low-level constructs like

redisTemplate
    .getConnectionFactory()
    .getConnection()
    .streamCommands()
    .xClaim(...);

It would be much more convenient to have a possibility to call high-level stream ops

redisTemplate.opsForStream().claim(...)

like for many other commands, especially while

redisTemplate.opsForStream().pending(...)

operation exists and is usually needed in the same scenarios.
