opaqueId property
Id of new on-vehicle mission, fence, or rally point plan (on upload to vehicle).
The id is calculated and returned by a vehicle when a new plan is uploaded by a GCS.
The only requirement on the id is that it must change when there is any change to the on-vehicle plan type (there is no requirement that the id be globally unique).
0 on download from the vehicle to the GCS (on download the ID is set in MISSION_COUNT).
0 if plan ids are not supported.
The current on-vehicle plan ids are streamed in MISSION_CURRENT, allowing a GCS to determine if any part of the plan has changed and needs to be re-uploaded.
