Fix builds for pythonPackages.azure-mgmt-*

[bendlas]

Don't merge until nixops is updated!

EDIT Nixops has received a package-private, pinned version of azure-mgmt-*, so this can be merged at leisure

Motivation for this change

Followup to the reverts in #52547

Revert the reverted updates and apply some build fixes on top

With this, nixops still fails, because it can't work with these versions, so this will need to wait until nixops is updated:

btw, if you want to reproduce the error, please do so with nixopsUnstable. nixops still fails for a different reason NixOS/nixops#1050

[bendlas]

these libraries have been updated in 3a49f98 2eb9ded 808e5d9 9f97782 7f80b2f

I'll pin the older versions in the nixops package, so that work on NixOS/nixops#1065 can progress independently.

It seems, the azure-mgmt-* builds are still failing: https://hydra.nixos.org/build/89652010 https://hydra.nixos.org/build/89671586

Haven't tested the fixes in this PR with the newer version, but should basically work ...

This build failure was ported to stable: #55757

@bendlas this doesn't apply anymore, could you rebase?

What else is preventing this from being merged?

Does nixops work with the updated packages, or do we need to keep the private ones?

[bendlas]

Can do. AFAICT, we don't have any consumers, other than nixops, though.

Does nixops work with the updated packages, or do we need to keep the private ones?

Unfortunately, NixOS/nixops#1065 needs to be resolved first.
