Fix issue with direct_functions and path behaviour

Browse Source 
- The path clipping / transforming behaviour must be turned-off
when we are not using direct_functions as is used in
faas-nomad and faas-ecs. This will need a change in each provider
to strip paths, but fixes a 404 error these users will see if they
upgrade to 0.9.2 or newer. 0.9.3 will have a this fix meaning
the whole un-edited path is passed to the provider when
direct_functions is set to false.
