    Make gate great again

    This patch combines two fixes into one patch to fix UT failures:

    * Fix MidonetInterfaceDriver.plug_new signature

      Since [1], the "LinuxInterfaceDriver.plug_new" signature includes a
      new kwarg, "link_up". Because "MidonetInterfaceDriver" inherits from
      "LinuxInterfaceDriver" and overrides "plug_new" function, the local
      implementation should include this new parameter.

    * Fix Mysql db migration schema
      Field "midonet_tasks.data" was defined as sa.Text() in db model but in
      migration script for mysql engine it is defined as Text type with
      lenght long enough to create LONGTEXT field in the DB. That caused
      problem with types of field in the db model and migration script.
      So this patch fixes that by using sa.Text() with LONGTEXT variant for
      mysql engine in db model.
