azure-mgmt-* packages don't build

[bendlas]

Issue description

I've already worked through the update, but let's revert for now, because the newer azure-mgmt-* packages also break nixops.

cc @olcai @FRidh

Steps to reproduce

$ nix-build <nixpkgs> -A pythonPackages.azure-mgmt-storage
...
configuring
sed: can't read azure/mgmt/storage/storagemanagement.py: No such file or directory
...

[bendlas]

nox-review shows nixops and nixopsUnstable as the only dependencies, so I went ahead and pushed those reverts. I'll submit the updates as a separate PR.

fixed and backported to 19.03

I'm not convinced this is fixed in 19.03:

nix-build -E '(import (builtins.fetchTarball "https://github.com/NixOS/nixpkgs-channels/archive/5c52b25283a6cccca443ffb7a358de6fe14b4a81.tar.gz") {}).pythonPackages.azure-mgmt-storage'

these derivations will be built:

5c52b25 is (as far as I can see) the latest 19.03 channel revision.

@ocharles hasn't landed in the channel yet:

nixpkgs/pkgs/development/python-modules/azure-mgmt-storage/default.nix

Lines 18 to 22 in 5c52b25

	preConfigure = ''
	# Patch to make this package work on requests >= 2.11.x
	# CAN BE REMOVED ON NEXT PACKAGE UPDATE
	sed -i 's|len(request_content)|str(len(request_content))|' azure/mgmt/storage/storagemanagement.py
	'';

Thanks, I did have a look at some files and could see some of the above commits had been cherry picked. I'm also surprised that it hasn't hit the channel despite being merged over a month ago?

[asymmetric]

I'm also confused, given how 5c52b25 is 6 days old and is in the channel.

EDIT: Oh I see, it has only actually landed in the release-19.03 branch 4 days ago.
