Document VOLTHA Resources

resources/docker.rst
resources/repositories.rst
--------------------------
  o Added a resources/ section in docs.voltha.org.
  o Display links for docker URLs and gerrit/github repositories.
  o rst table generation is partly automated using a list of resource
    names and a makefile target that can generate line items.
  o This logic should be built out so docker.rst and resources.rst
    can be fully auto-generated.
  o resources::gerrit repository urls have been populated in the table.
    Strange: url syntax is fine (matches manual navigation), gitiles is
    able to digest the url but only displays a white screen.  Might be
    missing a cookie or context the UI passes.  Will debug this later.
