[SVCS-256] Adding "undecoded_path" to providers

[AddisonSchiller]

refs: https://openscience.atlassian.net/browse/SVCS-256

Purpose

We need the un-decoded file name to distinguish between files with special characters. ie: "me/ow.txt and me%2Fow.txt" The decoding tornado does makes these files hard to distinguish.

Summary of changes

Added an "undecoded_path" variable to the base_provider. This gets set in the "prepare" function to be the undecoded_path received from the request. The path is pulled from 'self.request.uri'

QA

QA will come on individual tickets for providers
