Jaeger driver is not compatible with Jaeger native span ids

[Shoham Peller]

Let's say service 1, which reports to Jaeger using jaeger's clients, calls service 2, which uses osprofiler with a Jaeger backend.
Service 1 will pass span ids and trace ids for service 2 to use. Those ids will be in Jaeger's format - 64 bit ints.
The jaeger driver currently assumes the IDs are UUIDs, and therefor fails to convert them to ints.

The jaeger driver needs to be compatible with the given IDs, which are produced by jaeger clients.

    When shortening span-ids, check if they're already short

    If you're given an int, there's nothing to do, just return it
