"privilegeExecution" field will specify if protocol can perform file operation with elevated privileges.
Dolphin relies on `KFileItemListProperties` for enabling some of its context menu actions. Internally `KFileItemListProperties` uses `KProtocolManager` to determine if a location supports reading, writing,
deleting and moving. With these changes `KProtocolManager` will now check for the said field. Consequently, dolphin will be aware of our new file protocol and will show its context menu without any
action being disabled.
