resource: remote resource resolution fixes

- "remote" getter priority reduced to be below "environment" so that
  resouces placed into "~/.workload_automation/dependencies" by the user
  take priority over those pulled from remote locations.
- "filer" getter now uses a cache location for the resource rather than
  downloading to the local resource location.
