Switch traces exporter from Jaeger to OC

SignalFX APM backend heavily rely on span.kind attribute. If OC golang instrumentation used with Jaeger exporter, the span kind is converted to a part of Operation name and not passed as an attribute e8b55949d9/jaeger.go (L259-L268) .

This commit switches trace exporter from Jaeger to OC in go and java service to make sure span.kind is always correctly propagated.
