Improve execution time on Model deserialization

So I tried to migrate our usage of raw API calls to Microsoft Graph to your new release 1.1.0.
And I measured execution time with the bare-bones method time.time() before method call, time.time() after method call.

I've tried performing get requests for the endpoints: me, users, domains.

The results were that the sdk is on average 3.5 times slower than the raw call to API which I think a great deal.

Furthermore, I was curios where this overhead came from and I searched through the code with debug.
And the most time spent in execution is after the call to the rest api, when the sdk is building a model by deserializing the json object got from the request in a sdk specific object.

This execution time difference lead me to decide that I should postpone the migration until this is improved or fixed.

Comece rastreando a desserialização dos modelos do SDK após a resposta REST, que o issue identifica como a principal fonte de overhead. Reproduza a comparação relatada para os endpoints me, users e domains; a tarefa estará concluída quando for demonstrada uma redução mensurável no tempo de execução em relação a chamadas diretas à API.
