Description

Currently, the OpenTelemetryClientInterceptor is based on an external implementation of grpc client interceptors whose source code lies in the package grpcext.

To support the official grpc.UnaryUnaryClientInterceptor-, grpc.UnaryStreamClientInterceptor-, grpc.StreamUnaryClientInterceptor-, and grpc.StreamStreamClientInterceptor-interface, which are supported officially in grpc since v1.8.0, the source code of the _client.py-module is adapted.

Hereby, the design of the _client.py-module orientates itself strongly on the design of the _aio_client.py-module. Thus, the external implementation of the grpc client interceptors can be removed (package grpcext). Also, the RpcInfo-class in the utilities.py-module is not required any more.

The _aio_client.py-module must be adapted so that the _BaseAioClientInterceptor becomes independent of the _BaseClientInterceptor.

The test_client_interceptor_trace_context_propagation-tests are adapted according to the same test in the test_aio_client_interceptor.py-module to remove the dependency on the external implementation of the grpc client interceptors, which are located in the package grpcext.

The documentation of the code in the __init__.py is adapted accordingly.
