Title: Split common classes into zipkin-common

- Moved:
- `Annotation` (and spec)
- `Endpoint` (and spec)
- `IncompleteTraceDataException`
- `Span` (and spec)
- Left `Trace`, `TraceSummary` in `zipkin-server` since they're specific to the query service
- Left `ZooKeeperClientService` since don't want to introduce a ZK dependency in common project
- `IncompleteTraceDataException` can be later removed when we pull out the Thrift dependencies
