Expected Behavior

A feast application has a registry of type remote connected to a registry server.
The feast client invokes a an API on the feast registry that thrown an error, e.g. store.get_feature_service("foo") which raises
FeatureServiceNotFoundException from the registry server because foo is not a registered feature service.

The expectation is that the method invoked by the client raises the FeatureServiceNotFoundException and the application can detect it with:

try:
    fs = store.get_feature_service("foo")
except FeatureServiceNotFoundException
    ....

Current Behavior

The registy server always raises an _InactiveRpcError error instead.

This bug causes unexpected errors when the client invokes services whose implementation needs such expections to execute fall-back logic, like _get_feature_views_to_materialize.

Steps to reproduce

See Expected Behavior section.
