Mumi service

[Ludovic Courtès]

Hello Guix!

Commit 6ee87461e0466f8756ac01257abcae80f7fe17ca adds a Mumi service.
The goal is to use it in hydra/berlin.scm (in maintenance.git), as
discussed recently on #guix.

However, the currently packaged snapshot crashes when trying to retrieve
information about a bug:

Does that ring a bell, Ricardo?  Should we update to a newer snapshot?

Thanks,
