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.

* Fix test case names in TestNewOpentelemetryCfg
* OpenTelemetry: Remove redundant error checks
Introduces a FromContext method on the log.Logger interface that
allows contextual key/value pairs to be attached, e.g. per request,
so that any logger using this API will automatically get the per request
context attached. The proposal makes the traceID available for
contextual logger , if available, and would allow logs originating from
a certain HTTP request to be correlated with traceID.
In addition, when tracing not enabled, skip adding
traceID=00000000000000000000000000000000
to logs.
* use common traceID context value for opentracing and opentelemetry
* support sampled trace IDs as well
* inject traceID into NormalResponse on errors
* Finally the test passed
* fix the test
* fix linter
* change the function parameter
