Funny to see it succeeded on redis but failed on redis cluster and kvrocks. |

Hi, how about implement kv::Scan directly without go through Stream?

We could extract RedisCore as other services do and use Arc<RedisCore> here to avoid duplicate calls like conn_from_pool.

Which issue does this PR close?
Closes #.
Rationale for this change
Currently only read and write is supported for redis service.
After #5208 we can have a better support for kv scanning, so list supporting for redis is relatively easy to implement and can be efficient.
What changes are included in this PR?
We support (async) list operation for redis service via
kv::Adaptor::scanto fetch paged key lists with a prefix using Redis SCAN command.Are there any user-facing changes?
User now can perform list on redis schema.
