Add confirmation dialog on delete

[AxelRICHARD]

• I have checked that this feature has not yet been suggested by someone else.

Expected behavior

Sirius Web does not have an undo/redo mechanism yet.
When an element has been deleted, either from the Explorer view, from any representation, or any other view, there is no way to retrieve it.
All delete actions are executable in one click.
Any accidental click on a delete action can lead to the unwanted loss of data.
By extension, some one-click actions may lead to unwanted consequences.

A confirmation dialog should be displayed when a delete action (click on the delete tool on a node, click on DEL key on a node, click on the delete menu item on an object in the Explorer view) has been called.
This dialog should avoid or drastically minimized unwanted loss of data.
This dialog should have the possibility to be disabled.
