apolcyn 23d34cdd84 testing: create test client for XDS federation integration tests (#9798) ... This client can be used as a part of XDS federation integration tests. It can concurrently perform RPCs with different stubs using different underlying XDS servers. For example, one might perform proxyless service mesh and DirectPath RPCs in the same process with flags like: ``` --server_uris=xds:///${PSM_TARGET},google-c2p:///${DIRECTPATH_TARGET} \ --credentials_types=INSECURE_CREDENTIALS,compute_engine_channel_creds \ --test_case=rpc_soak \ --soak_iterations=10 \ --soak_max_failures=0 \ --soak_per_iteration_max_acceptable_latency_ms=2500 \ --soak_overall_timeout_seconds=300 ```		2023-01-13 11:55:08 -08:00
