Description

More JSON serialization fixes

• Do not quote numeric time fields (they should be less than 55 bits)
• Use jackson for JSON serialization, not an ancient version of jetty
• Implement JSON deserialization as well as serialization in htrace-core
• Shorten "time" and "msg" fields to "t" and "m" in TimelineAnnotation
• fix ToString method that was using "%08x" rather than "%016x"
• REST methods should take hex values for span IDs, not decimal
• Add TestMilliSpan to test round-tripping JSON in htrace-core
