    Remove ryu plugin

    Ryu plugin was marked deprecated in Juno and will be removed for Kilo.

    Also, mention Ryu team's recommendation for ofagent in
    doc/config-reference/networking/section_networking-plugins.xml

    We (Ryu team) recommend users to migrate to ofagent, on which
    we aim to concentrate our development resources by this deprecation.
