Option to enable tracing level metrics without full tracing

[jmccaull]

Is there any opposition to having the option to enable full tracing metrics without having trancing data returned to the consumer? Essentially we would like to have the bean TracingInsturmentation with tracing-enabled still = false

@oliemansm, thoughts? did a quick PR: #240. We would like to replace some of our custom metrics instrumentation with this

I've merged your PR, had no problem with this. Just come to think of it after the merge: could you update the README to document the possible props?

@oliemansm I think this should cover it, lmk if you want any more in depth. Thanks!
#241

@jmccaull That'll do, thanks!

Hello @jmccaull @oliemansm
Thank you for this feature, this is exactly what we need.
I've noticed though that additional-spring-configuration-metadata.json is still expecting a Boolean for graphql.servlet.tracingEnabled field which doesn't allow our application.yml config to set it to metrics-only which is a string. Am I missing something? 🤔
I don't have rights to push to this repo, but the change would be something like this:

additional-spring-configuration-metadata.json:

...
    {
      "name": "graphql.servlet.tracingEnabled",
      "defaultValue": false,
      "type": "java.lang.String"
    },
...
