Fix python version
Update ubuntu version

* Activate CI for newer python versions

* Nose is no longer maintained - no support for python 3.1x
Replace Nose with Pytest, drop sniffer support (depends on nose)

* Relax python version requirement

* Add coveragespace

* Remove Pipfile - makes it impossible to support multiple python versions
