[Project] Find my device over Mesh

[Aras14HD]

Is your feature request related to a problem? Please describe.
Current Find my Device services use a server that the device to be found is constantly connected to via the internet. This has multiple problems:

1. It enables tracking by the service operators (if done well only ip history of account)
2. If the servers go offline, you can't find your device
3. It only works if the device has an internet connection (with this solution the device still needs to be near other devices to be reachable without internet)

Describe the solution you'd like

Location requests:

A node sends an authenticated and encrypted route message asking for the location of the device to be found, if the authentication is legitimate, the precise location (gps) is sent back.

Play sound, Lock device, etc.

A node sends an authenticated and encrypted route message asking for an action to be taken, the device adressed does that action and sends a status (accept/reject) back.
