Support other tracing provider other than Jaeger via OpenTelemetry

[roystchiang]

Is your feature request related to a problem? Please describe. Currently, Cortex only supports Jaeger as backend for tracing. I would like the ability to use other tracing providers such as AWS X-Ray.

Describe the solution you'd like The current tracing client only supports Jaeger, while OpenTelemetry supports Jaeger and other tracing providers.

The integration with OpenTelemetry should be backward compatible in a way such that existing clusters using Jaeger do not have to run OpenTelemetry collectors.

Describe alternatives you've considered Instead of integrating the tracing on Cortex, we submit PR for weavworks/common where tracing is currently configured. I wanted to see what the maintainers' opinions are.
