    Support setting rpc-response-timeout and report-interval

    These two options are set in neutron-api charm centrally,
    this patch allows neutron-gateway charm to continue doing:

    1, rpc_response_timeout
       Used by all neutron agents, so both neutron-gateway charm and
       neutron-openvswitch charm get it via it's relations and set it
       in [default] of neutron.conf

    2, report_interval
       Used by all neutron agents, so both neutron-gateway charm and
       neutron-openvswitch charm get it via it's relations and set it
       in [agent] of neutron.conf

    This patch also syncs charmhelpers for setting them centrally.
