Description
We have two methods of interacting with the API backend: gRPC (default) and HTTP (used when client is created with google.cloud.logging.Client(_use_grpc=0) or DISABLE_GRPC is set).
This is implemented using two _*API implementations: One in _http.py and the other in _gapic.py. It looks like in some cases, they return different values (_http returns a page iterator object directly, while _gapic often converts it to a generator. This confuses users who expect high-level APIs to act consistently regardless of the implementation used.
I suggest we refactor _http.py to be consistent with _gapic.py, and add tests to make sure they act consistently
