I've refactored the user query code to be able to use it also on the
integration configuration page. Now, items can be re-organized as in
the user query list.
* Add a query configuration page
Before, there was no way to modify a user query. Thus you need to
create a new one and delete the old one afterward.
Now, every user query can be modified if needed. They have their
own configuration page on which it can be modified or deleted.
* Change drag and drop action on queries
Before, the drag and drop action needed to be validated by submitting
the form to be persisted.
Now, it's done automatically after the query is dropped to its final
location.
Before, it was nearly impossible to know exactly where the dragged
item will land when dropping it.
Now, there is a visual marker to show the drop location.
An HR tag is inserted dynamically in the DOM. It's possible to style
it if needed.
* Add user query manual sorting
Before, to change the user query order, you'll have to delete them
and recreate them. It was not really efficient.
Now, you can drag and drop them to ease reordering.
See #2216 and #2015
* Remove cancel action on user query configuration
Before, the cancel action was useless since it was not wired.
Now, there is no cancel action.
See #2015
