TODO: Use individual Azure packages

[blag]

In version 5, the azure metapackage now refuses to install. The azure package was broken up into a bunch of smaller packages, so we need to use those packages individually instead of relying on the metapackage to install everything for us. PR #14 kept CI passing, but we will need to refactor eventually.

More information on the azure change is here: Azure/azure-sdk-for-python#10646.

And this might complicate #6.

This is now a requirement. I tried several things to try and patch things up and get CI passing again to no avail.

Whoever wants to use the azure pack needs to update usage of the azure libs to newer versions.
#17 might be a good starting point. I adjusted a couple things based on pylint output and reading a few things in the azure-mgmt-resource lib code. But I don't see how to fix everything else, so someone else needs to carry it forward.
