fix: update default tracing endpoint to oltp protobuf endpoint

currently the otel sdk is used to export metrics in the protobuf
format, for the sake of consistency this commit makes sure that we
use 4318 with /v1/traces as the default jaegar tracing endpoint
use port 4318 with /v1/traces for the default jaegar tracing endpoint
instead of port 14268 with /api/traces endpoint.
