[Discuss] Support different stores for different projects in one single feast-serving container

[randxie]

Move the discussion from slack to github issue for visibility.

We have a use case that require using different redis clusters for different projects, e.g. shared features can be placed in a shared redis cluster and team-specific features can be placed in team redis cluster. We will have a single request that read from multiple clusters.

If we think this is the direction moving forward, we can brainstorm implementation details here.

@randxie thanks for creating this issue. One question: What do you mean across different projects? Do you mean a single request should be able to read from both different clusters and across projects? Meaning you want to do something like project.feature_table.feature? Or by project do you mean your internal company projects or use cases?

Sorry for the confusion, by project, I mean the project in Feast (project.feature_table.feature). We mapped project to team internally, where each project will have its own online store (redis cluster).
