chore: Suppress alpha warnings in test. Fix entity serialization in test

[adchia]

What this PR does / why we need it:
The make test-python and make test-python-integration-local commands were littered with warnings. This suppresses that to make for a better testing experience.

Note: test_lambda fails when switching to entity_key_serialization_version=2 so this temporarily keeps it at 1 for that test

ideally these imports should come from feast.feature_service, feast.feature_store, etc.

Also, utils :(

[achals]

This is probably becase we need to build and push a new docker image (that uses the new version number). The docker image isn't automatically updated via CI at the moment.
