Improve translate5 webhooks

We need to have flexible way to define custom callbacks based on workflow action events.

The idea how to solve this:

• add new column in the workflow action table called webhookname
• the webhook name will be unique for each wanted custom callback. For example:

      for trigger: handleAllFinishOfARole and step translation and state finish we can define as webhookname: handleAllFinishOfARole_default_translation_finish
      where the default is the workfolw, translation is the step and finish is the status * then in the UI you should type the webhook name as key and the url as a value (here the bug for non editable key should be fixed.)

• then in the triggerCallbackAction the configured values will be evaluated

Until we have implemented the UI management of the workflow action, for defining new web-hook we will always do it with sql alter file in the workflow action.
