    Prevent L3 agent looping calls from hanging

    This patch adopts several measures to prevent _sync_routers_task
    and _rpc_loop from hanging because of subprocess.Popen.communicate
    not returning.

    1) Perform a sleep everytime a command is completed, similarly to
    what is done in openstack.common.processutils.execute
    2) Disable by default GARP, as kernel crashes caused by arping
    have been observed
    3) Prevent a non-critical keyerror in _router_removed from triggering
    again a full sync, which might put the system under significant load.

    This patch also adds debug log statements aimed at improving the
    ability of debugging similar failures.
