Simple go wrapper for the OVH API

 Lightweight Go wrapper around OVH's APIs. Handles all the work including
 credential creation and requests signing.
 .
 This wrapper will first look for direct instantiation parameters
 then OVH_ENDPOINT, OVH_APPLICATION_KEY, OVH_APPLICATION_SECRET and
 OVH_CONSUMER_KEY environment variables. If either of these parameter is
 not provided, it will look for a configuration file.
