This commit does the following:
- fully defines the inventory rather than having test-prepare-host.yml
add containers to it
- removes installation of lxc_python2 library, since this is no longer
necessary
- updates test-prepare-keys.yml to use localhost instead of 127.0.0.1,
uses become_user=jenkins instead of become=false, and removes
redundant connection
- updates test-prepare-host.yml by removing redundant become and
connection options, changes 127.0.0.1 to localhost, and removes
mocking ansible_env
- groups vars in test-install-glance.yml and test-install-keystone.yml
into test-vars.yml so they're only defined once
