Making the dependency adal optinal

[atolj]

Hi folks,

I'm currently using the version 'kubernetes==8.0.0a1' and encountered that the ADAL dependency was added. This makes it more difficult to package a container image as it pulls additional dependencies and the image size increases. The following tweet illustrates it perfectly.

It would be nice if the dependency is only added under extra_require.

It has also the effect that, when I'm building an alpine image I have to install additional packages like [ build-base, libffi-dev, openssl-dev] or in another case [gcc build-base linux-headers python3-dev ca-certificates python3-dev libffi-dev libressl-dev], which bloats the container further.

I'm currently not sure where the dependency is used.

I were sure I were doing something wrong when making Alpine-based images, but the packages you mentioned makes alpine3.7 images about 300 MB just to make sure the kubernetes package is installed.
