Backport openstack module_utils from devel

Pin modules to the matching stable-1.9 branch

There were no modules in 1.9 that used these functions, and there are
people who would like to use devel modules with 1.9 ansible.

This is to keep module changes on devel from breaking when ran on
stable-1.9 Ansible.

Vendorize match_hostname code so that ansible can push it out to clients along with the code that uses it.

Manually apply changes from 952166f4
because git won't cherry-pick successfully

Manually pull in changes from ca2f2c4e
as git won't cherry-pick those files successfully.

The current code expects "uname -W" on AIX to always succeed. The AIX 5
instance I have doesn't support the -W flag and facts gathering always
crashes on it.

This skips some WPAR handling code if "uname -W" doesn't work.

open_url() is suitable for use outside of a module environment.  Will
let us use open_url to do SSL cert verification in other, non-module
code.

and the test_win_copy integration tests that depend on the checksum
have been updated in this change too.

Handle when role_dependencies is None.

Fix KeyError which occurs when not-existing entry is tried to be removed.
