dev-python/stomp-py: new package

Python STOMP client library + CLI tool. No tests because running them
requires either Docker or carefully setting up several different
messaging servers. May or may not support pypy3, for the time being
this is blocked by dev-python/docopt.

+# stomp.py test suite requires quite a few appropriately configured
+# messaging servers (as of 6.1.0: RabbitMQ, ActiveMQ, ActiveMQ Artemis,
+# stompserver). Upstream relies on Docker to provide those servers, however
+# doing the same in src_test would require both granting the portage user
+# extra permissions and packaging the base image (trying to download it
+# on the fly would violate the network sandbox).
+# Side note: PyPI tarballs do not include tests.
