Is your feature request related to a problem? Please describe

Some third-party components already have OTEL instrumentation and these don't allow setting custom trace exporter. An example could be kube-apiserver which requires endpoint to accept GRPC spans. It would be useful to have GRPC support in VictoriaTraces too.

Describe the solution you'd like

A separate port accepting GRPC spans
