https://packages.ubuntu.com/bionic/gnocchi-api seems to indicate it's coming straight through an import from Debian, where the current OpenStack ecosystem is packaged to use only Python 3.x. This probably makes it incompatible with the official Ubuntu OpenStack packaging which still relies on Python 2.7. If I were to guess, Gnocchi isn't included due to it not officially being part of OpenStack any longer (the developers decided to move out of OpenStack and form their own community around Gnocchi in March of 2017).
