0.23.0 (2022-08-02)

This release adds many bug fixes as well as new functionality:

• Support for a Snowflake online store
• A batch materialization engine interface, which now makes materialization a pluggable component. There are two reference implementations already (local, which was the former default, and an AWS Lambda engine which scales up materialization with Lambda)
• A to_remote_storage method in RetrievalJob (the output of get_historical_features). This makes methods that were already implemented (e.g. to_gcs or to_s3) now visible at the interface level. The Lambda materialization engine implementations use these methods to unload data to a bucket before scalably loading this data into the online store.
• Improvements to Feast Web UI + SavedDatasets
