This reviews the code and fixes up suggestions made by team for
the HTTP paths PR #789.

- Removed feature-flag (this is backwards-compatible, so I see
no value in adding the flag)
- There was a URL transform happening for calls proxied to the
back end, I changed this for the nil-transform - i.e. it does not
change anything in the URL
- Introduced variables to describe the regex indicies used in
the URL trimming.

Tested with Docker Swarm with a ruby-microservice, with
system calls and with function calls using the UI.

Make 'URLPathTransformer' interface and implementation to do the function prefix trimming instead of baking it in.  Also add a configuration option, 'pass_url_path_to_functions' to control whether the full path is passed to the functions or not.

Previously, only the query string of the URL was passed through the Gateway.
With this change, the entire path requested by the client is passed through as well as the query string.

While fwatchdog already supported passing the path through, in practice this would not happen
since the Gateway would have swallowed it before forwarding the request to the watchdog.

With this change, the path portion after the function name is added to the Http_Path environment
variable, provided that cgiHeaders are enabled.  This is similar to the of-watchdog equivalent.
