Feedback of Version 1 and Version 2

With reference to the version description https://github.com/microsoftgraph/msgraph-sdk-php/blob/dev/UPGRADING.md and request for comments regarding the new syntax.

I don't know what the consensus was but my 2 cents would be to support both (although looking at the source code it looks like the v1 syntax is no longer supported) . My opinion we should remain as close to the graph endpoints as possible, abstracting away from the ms-graph endpoints makes the interfacing very subjective and far from obvious - I hope this is not too late. The ability to modify attributes to adapt to different scenarios has to be easier with the V1 as well - I would have thought.

// v1.x
$response = $graphClient->createRequest('GET', '/users/userId/messages')
->setReturnType(Model\User::class)
->execute();
// v2.0
$response = $graphServiceClient->users()->byUserId('userId')->messages()->get()->wait();

Start with UPGRADING.md and compare the v1 and v2 request examples cited in the issue. This feedback needs a maintainer decision on syntax compatibility and attribute customization before implementation can be scoped; done would mean an agreed direction and corresponding update or change.
