Adds support for logs (specify level), metrics (enable metrics and Prometheus /metrics endpoint
and traces (jaeger or otlp) for standalone API server. This will allow any grafana core service
part of standalone apiserver to use logging, metrics and traces as normal.
* Pass OTEL sampling config to plugins
* fix capital letters
* Do not pass sampler env vars if sampling is not configured
* Add tests
* PR review feedback
* Simplify tracing env vars logic
* Update test to reflect pkg/infra/tracing behaviour
This commit replaces `os.Setenv` with `t.Setenv` in tests. The
environment variable is automatically restored to its original value
when the test and all its subtests complete.
