Add open telemetry tracing to the SDK

[craigpastro]

Describe the feature request?

In order to get more visibility into the request lifecycle it would be nice if there were traces, at least at the top-level methods. We make a lot of requests using this SDK and currently use a TracingClientWrapper, but it would be nice if tracing were built-in.

New or Affected Resource(s)

Most, if not all, resources.

Additional Information?

Ideally, this would just involve adding a couple of lines to top-level methods. For example, add

var tracer = otel.Tracer("github.com/okta/okta-sdk-golang/okta")

to okta/okta.go and then, e.g., in okta/user.go the use of this tracer would look something like:

... stuff

func (m *UserResource) CreateUser(ctx context.Context, body CreateUserRequest, qp *query.Params) (*User, *Response, error) {
    ctx, span := tracer.Start(ctx, "CreateUser")
    defer span.End()
    ...
}

... rest of stuff

I'm happy to create a PR if you think this is something that you wish to add.

Thank you!
