Support for AWS Xray as a source of OTEL traces

[cloudronin]

Currently Pythia only supports Jaeger as the source of traces, it would be good to support
https://aws.amazon.com/xray/ as well for AWS users who use Xray as their distributed tracing backend

Xray does have its own OTEL collector distro
https://github.com/aws-observability/aws-otel-collector

So the pythia all-in-one might need to use that instead
