Pecan doesn't work with noauth auth_strategy

[Jakub Libosvar]

All fullstack tests fail because server is unable to server GET requests:

Switching web_framework to legacy works so it's related to pecan switch.

I'm not very familiar with pecan but from what I saw so far I think pecan now works only with keystone auth, while fullstack doesn't use auth.

neutron.context is added by keystonecontext factory that is not used by noauth
