apply_materialization for Remote Registry fails for Stream Feature Views #4271

Expected Behavior

apply_materialization for Remote Registry should work for Stream Feature Views. Discovered as part of #4257 when running integration tests.

Current Behavior

apply_materialization for Remote Registry throws the below error when trying to materialize a stream feature view:
TypeError: Parameter to MergeFrom() must be instance of same class: expected <class 'feast.core.FeatureView_pb2.FeatureView'> got <class 'feast.core.StreamFeatureView_pb2.StreamFeatureView'>.

Steps to reproduce

1. Setup Remote Registry
2. Call apply_materialization and pass a stream feature view as the feature view.

Specifications

• Version: Python 3.9
• Platform: Mac OSX
• Subsystem: Sonoma 14.4.1

Possible Solution

ApplyMaterializationRequest of the RegistryServer proto should be updated to allow the StreamFeatureView proto to be passed when making the request from Remote Registry via RegistryServer.
