Support for Firestore in Native Mode

[natsoule]

Is your feature request related to a problem? Please describe. The current Feast online store for GCP implementation requires Firestore in Datastore mode. Firestore can only be in one mode at a time per GCP account. You cannot use native mode for some applications and Datastore mode for others within the same account. Adding a feature store to an existing GCP account that uses native mode would not allow us to use the online store.

Secondly, Datastore is deprecated. Presumably Google does not want to support it forever, and there may come a time when Google no longer allows new Datastore implementations.

Describe the solution you'd like Feast should support Firestore in native mode.

Describe alternatives you've considered Creating a separate GCP account is certainly a possibility, but an inconvenient one. Creating a new account at many companies would require approvals and setup.

Additional context Add any other context or screenshots about the feature request here.

Thanks for bringing this up @natsoule - naively seems like we'd need to create a new online store implementation using https://googleapis.dev/python/firestore/latest/index.html.

Happy to review PRs from the community for this!
