Update to v1 (1.0.3)
    
    Upstream stopped vendoring dependencies in 1.0.0.  F31+ has those
    dependencies packaged, but in order to update earlier branches we must
    generate our own tarball with vendored dependencies.
    
    Additionally this commit updates the plugins to v1 compatible versions:
    
    - dnsproviders 0.3.0
    - geoip c06787a76821ab7852dc1a5219dd5c05d904dce4
    - realip 6df827e22ab8cd5ea90e0844ff29cf62b95127f9
    
    The geoip plugin gained a dependency on github.com/mmcloughlin/geohash,
    which is also not packaged until F31.  We will bundle it.
