* [feature] Add http trace exporter, drop Jaeger Jaeger supports ingesting traces using the OpenTelemetry gRPC or HTTP methods. The Jaeger project has deprecated the old jaeger transport. * Add support for submitting traces over HTTP * Drop support for the old Jaeger protocol * Upgrade the trace libraries to v1.17 Fixes: #2176 Fixes: #2179
