    Store the actual UUID of obj_id in Senlin database for webhook create

    In 'webhook' DB table, it has a field named 'obj_id' to reference a
    target which the webhook will act on. Now if we create a webhook
     with target name, then it will store the target name in the 'obj_id'
    field of 'webhook' table. Triggering this webhook maybe lead to
    unexpected result. An example is as following.

       1. Create the first cluster named 'cluster1'
       2. Create webhook on 'cluster1' with CLUSTER_SCALE_OUT action
       3. Delete the cluster1
       4. Create a second cluster also names 'cluster1'
       5. Trigger the webhook which will result in scaling out the
          second cluster.
