Had to add a _service to check out 0.31.0 from git since it's not tagged.
The commit was obtained from looking at the changelog at
https://github.com/jstasiak/python-zeroconf/blob/master/README.rst
and the commit history.

- Add patch to disable some tests that fail in obs:
* disable-tests.patch

- update to 0.31.0:
* Separated cache loading from I/O in ServiceInfo and fixed cache
lookup (#356), thanks to J. Nick Koston.
The ServiceInfo class gained a load_from_cache() method to only
fetch information from Zeroconf cache (if it exists) with no IO
performed. Additionally this should reduce IO in cases where
cache lookups were previously incorrectly failing.
- update to 0.30.0:
* Some nice refactoring work including removal of the Reaper
thread, thanks to J. Nick Koston.
* Fixed a Windows-specific The requested address is not valid in
its context regression, thanks to Timothee ‘TTimo’ Besset and
J. Nick Koston.
* Provided an asyncio-compatible service registration layer (in
the zeroconf.asyncio module), thanks to J. Nick Koston.
