[FEATURE]: google-apis-* tracing support #5495

Gem Name

googleauth, google-apis-core, google-cloud-storage...

Gem Version(s)

1.x upwards

Describe the goal of the feature

I'm looking to see what do you think about adding tracing support to the google SDK for google cloud, in a similar way like you're doing for the aws sdk.

Is your feature request related to a problem?

No response

Describe alternatives you've considered

We're already tracing the underlying HTTP calls via the ddtrace integrations for the respective clients, but it'd be great to also scope operation types to specific google cloud service calls.
