Add interop tests for gRPC Python. py_proto_library rules are added to
src/proto/grpc/testing/BUILD since grpc_proto_library is not compatible
with py_* rules.
'requests' python module is added to requirements.bazel.txt as it is a
dependency for google-auth. Previously, this was installed through
tools/run_tests/helper_scripts/build_python.sh before running tests.
If the last reference to a Python object is at module scope, when
its destructor is run before program termination it may find that
the globals it requires no longer exist. Destructors of objects
likely to be stored at module global scope need to check that
globals exist before attempting to use them, to avoid warnings
being printed by the Python interpreter.

Add Bazel rules for building and testing grpcio_health_checking.
An unofficial fork for rules_protobuf is used for now as it incorporates
a change (#196 by duduko on the upstream repo pubref/rules_protobuf)
which allows the protoc compiler to compile generated protos too. This
was not merged because the change was failing for golang, but works as
expected for Python.
This is needed because grpcio_health_checking fetches it's proto file
from a different directory (previously achived through setup.py) and
thus needs to be moved to the required location within bazel-genfiles
using a genrule.
