Add `NOMKSTREAM` option to `XADD` command

[mp911de]

Hi, this is a first-timers-only issue. This means we've worked to make it more legible to folks who either haven't contributed to our codebase before or even folks who haven't contributed to open source before.

If that's you, we're interested in helping you take the first step and can answer questions and help you out as you do. Note that we're especially interested in contributions from people from groups underrepresented in free and open source software!

If you have contributed before, consider leaving this one for someone new, and looking through our general ideal-for-contribution issues. Thanks!

Problem

Redis 6.2 introduced a new flag, NOMKSTREAM to its XADD command. We want to support this flag in Spring Data Redis.

Solution

We have XAddOptions as a collector for additional arguments for the XADD command. Extend XAddOptions (for the imperative API) and AddStreamRecord (for the reactive API). Add tests to verify this functionality.

See also https://redis.io/commands/xadd for further information.

@mp911de may I help ?

[mp911de]

Sure. I assigned the ticket to you. Let me know if there's something we can help you with.

@mp911de I am sorry but I just notice that it was a first timer only issue and not an ideal for contributions but I already participated in such issue with spring-boot project so it is not really fair if I take it in order to respect the first timers only concept. Are you agree with me ?

[mp911de]

No worries. We've announced this issue for the second time after quite some time of inactivity. Since you're new to Spring Data, technically you're a first-timer here.

[mp911de]

Any update here? Is there something we can help you with @omlip?

[omlip]

@mp911de You did well to remind me.
In fact the goal of this task is "just" to extend the 2 classes and backed fields to supprot this flag or this task is going further and add a deeper support for nomkstream flag ?
