Support for `scan` in `RedisTemplate`

[lc77254]

Recently I use redis scan in my project. But I found that I can't use it in RedisTemplate directly and use RedisCallback instead. It was implemented in ReactiveRedisTemplate, is there any issue when implement it in RedisTemplate? If not, I would like to implement it.

Thanks for reaching out. I think that mostly no one asked for this feature yet. A specialty with SCAN is that the underlying cursor requires a connection to work on so the connection must not be closed/released after the command (see DefaultSetOperations.scan(…) for example). Other than that, feel free to submit a pull request.
