Review comment:
In testing I set `general.opentelemetry.enabled` to `true`, but did not
have the java agent jar or any other OpenTelemetry jar on the classpath. It
still logged that trace was enabled. I think in this method and in `enable()`
we need to also test whether the result of `getOpenTelemetry()` is equal to
`OpenTelemetry.noop()`. We should probably consolidate the logging in
`initializeTracer`, `enable`, and `disable` to one method. Something like:
```
private static void logMsg() {
boolean isEnabled = enabled &&
(!getOpenTelemetry().equals(OpenTelemetry.noop());
LOG.info("Trace enabled: {}, OpenTelemetry instance: {}, Tracer instance:
{}", isEnabled,
getOpenTelemetry().getClass(), getTracer().getClass());
}
```
