[FEATURE] Integrate with redis vector sets as `EmbeddingStore`

[Jacopo47]

Is your feature request related to a problem? Please describe.

No.
I know that there is already a community module that integrates with redis (full-text search module),
but since the latest version of redis released a set of commands dedicated to vector sets I think that could be useful build an embedding store on top of it.

My two cents are to not substitute the current integration but add a separate module that integrates with redis' vector sets.
In this way both the integrations will be supported.

Describe the solution you'd like

Create an embedding store on top of redis' vector sets

Describe alternatives you've considered

No

Additional context

I worked a bit on it in this repository: https://github.com/Jacopo47/langchain4j-redis-vectorsets

@riferrei Thanks for your passion! I think we just need a new class named like RedisVectorSetsEmbeddingStore instead of a new module. WDYT?

Hi @riferrei ,
Hi @Martin7-1 ,

I'll try to create a PR asap in order to share my work with you and discuss together about how to collaborate on it.
Right now I'm waiting for a feature to been developed in Redis: redis/redis#14499 (comment)

Without this Redis' feature there are filters that are not working, indeed integration tests are failing.

@Martin7-1, yes... I agree. We just need a new representation for this embedding store.
