Replace SET NX GET in rueidisaside with Lua when using Redis < 7

[rueian]

Currently, rueidisaside uses the latest syntax SET NX GET to acquire a lock before populating values to be cached.

rueidis/rueidisaside/aside.go

Line 141 in 0124d4a

val, err = c.client.Do(ctx, c.client.B().Set().Key(key).Value(id).Nx().Get().Px(ttl).Build()).ToString()

The latest syntax is the cause that makes rueidisaside support only Redis >= 7. It would be nice if we had an option to config rueidisaside to use a Lua script instead of the SET NX GET, so that we could support more users with old Redis.
