Ability to "lock" a group to parent to prevent drag & drop
Background/use-case:
While the ability to click-and-drag to move items around on the Resources tree is absolutely fantastic, we've had a few but impactful occurrences where administrators accidentally moved groups when their mouse shifted slightly while clicking and it threw their target into the group above/below it. While a simple mistake with a simple fix to undo, some accidental moves have gone unnoticed until users report missed alerts due to alert filters/rules no longer matching.
The Ask:
It would be nice to have the option on groups & devices to prevent the ability to drag-and-drop that specific item (i.e. lock it to its parent group). After a very brief look at the current UI code, it might be as simple as this option not setting the related drag-and-drop CSS classes on that node of the tree.
