Split the SDK into smaller parts

Is your feature request related to a problem? Please describe the problem.

The MS Graph SDK for Python comprehensively covers all Graph APIs and provides full models for all data structures.

This is good software library design, but it has one significant downside: It blows up the size of the library tremendously.
In the context of compiled languages, it wouldn't make much difference, because the final result would only include those parts that are actually used.

With an interpreted language like Python however, all the parts have to be included in every project that uses the library.
At this point, the library is already at 380 MB, which exceeds the limit for certain serverless runtimes, and also adds unnecessary storage and data transfer costs.

Describe the solution you'd like.

Please decrease the footprint of the SDK or split it into smaller parts, so only the services that are actually used have to be included in a project.
