Richard Belleville 7adf2f5c65 Implement first pass at Python XDS interop client.
I discovered a couple of existing shortcomings while implementing this
client that mean this is *not yet ready for inclusion in CI*. I
nonetheless want to get an early review and integrate this to the master
branch, in the interest of small easily reviewable code changes.

The first problem was that the bazel build has apparently never pulled
roots.pem in as a data dependency. This appears not to have been a
problem until XDS enters into the mix. This has been added into the
Bazel build with a small change to the pyx_library rule.

The larger problem is that there is currently no public Python API to
get a peer's identity from the client side. This is crucial to
determining the correctness of an interaction of a client-server pair
under XDS. I intend to add such an method to the RpcContext interface in
an upcoming PR and use it in the interop client. For the moment, I
simply fake the peer details.

Finally, I add a knob to run_xds_tests.py allowing multiple instances of
this test to exist at once. Multiple instances forwarding to the same
port cannot exist on GCE, so this enables multiple people to run tests
at the same time.

Pau Freixes bb2c94f0e2 Fix random segfaults when gRPC call resources are released
Due to the GC work for breaking reference cycles the internal
attributes of the _AioCall object were cleared and initialized
with None in aims of releasing refcounts for breaking direct or
indirect references.

Once the clear was done, the deallocation of the _AioCall would
fail since the pointer to gRPC call was cast to an invalid object,
no longer was a GrcpWrapper object but a None object, returning a
NULL as a value for the attribute call.

Pau Freixes 77df7f5f17 Client unary unary interceptor
Implements the unary unary interceptor for the client-side. Interceptors
can be now installed by passing them as a new parameter of the `Channel`
constructor or by giving them as part of the `insecure_channel`
function.

Interceptors are executed within an Asyncio task for making some work before
the RPC invocation, and after for accessing to the intercepted call that has
been invoked.
