the docs say that the PAGURE_CI_SERVICES key Defaults to: None - the default config file sets this to the empty list - but i get an error if this key is missing from the config file:

  File "/mnt/data/code/pagure/pagure/__init__.py", line 169, in <module>
    or APP.config['PAGURE_CI_SERVICES']:
KeyError: 'PAGURE_CI_SERVICES'

i am assuming that this is not the intended behavior because other of the new keys (such as INSTANCE_NAME) do have a fallback and no error is thrown if this key is missing
