Code review comment for ~tore.lonoy/cloud-init:hashed-chpasswd-support

Tore,
I went ahead and modified some of the integration tests to have a test for this.
and then proposed https://code.launchpad.net/~smoser/cloud-init/+git/cloud-init/+merge/320986 for merge into your branch.

Can you review that ?

Also, i did nto realize before that you hadn't signed the contributors agreement.
Please do so as described in HACKING.rst
