Public Safety USS should inform officer when there is lack of info

[myspri]

Some USS's may throw an exception while querying for an operation within an area or by uvin.

Pub-safe USS should handle this situation gracefully and inform the officer that some info might be missing.

There are two situations:

1.USS, potentially operating the vehicle may fails to return result when querying by uvin.

When this happens, pub-safe USS may populate vehicle info details, but include additional info to say "Encountered problem while retrieving operation info from USS"

2. A USS may not throw exception while returning operations in an area, thereby causing public safety USS to exclude potential operations.

   There is no easy way to notify the officer in this situation since the API only returns a list operation.

@myspri is this an implementation issue due to some USSs not being involved in public safety testing and thus not implementing those queries? I guess I'm asking if this is just a current implementation problem and if we would expect it to not be a big deal in the long run since each USS would be properly checked out to respond appropriately to such public safety queries.
