feat: add 'GoogleAPICallError.error_details' property (#286)
Based on 'google.rpc.status.details'.
Prior to this commit, the package handled both missing and present grpc consistently. However, the following condition in exceptions.py:
try:
import grpc
from grpc_status import rpc_status
except ImportError: # pragma: NO COVER
grpc = None
rpc_status = None
means that if grpc_status module is not installed, the exception module behaves as if grpc wasn't present even though other modules (notably tests) behave as if it was present. As a result, people having one but not the other module installed get a bunch of test failures because grpc-based tests are run but e.g. the exception module's from_grpc_error() function fails since grpc is forced to None.
This is especially problematic since grpcio-status is a new optional dependency, and since it's not packaged on Gentoo, we'd effectively have to force people to uninstall grpcio.
Environment details
- OS type and version: Gentoo Linux

python --version3.8.12, 3.9.7 - pip version:
pip --versionn/a google-api-coreversion:pip show google-api-core2.2.0, 2.2.1, git master (d2a729e)
