    Set the default ``Backend.lookup`` timeout to 2 seconds

    In order to broadly cover the issue described in the referred bug,
    this patch sets a default timeout of 2 seconds in the
    ``ovs_idl.Backend.lookup`` method.

    This timeout should cover most of the situations where the IDL local
    cache update is delayed. This patch does not change the default
    behavior, except it will not fail if the DB cache is synchronized
    within 2 seconds.

    If we don't pass the notify handler or the backend does not implement
    one, in case of not finding the requested register, the method will
    raise like before.

    ovsdbapp library is bumped to version 1.10.0 to receive the change
    that introduces the active wait in ``Backend.lookup`` and adds the
    timeout parameter to the method signature.
