Update/Removal of pinned Oslo Messaging and Middleware for kilo

[Kevin Carter]

In the openstack_other.yaml file the libraries oslo messaging and middleware are pinned which break OpenStack services for Kilo.

These Items can be found here: https://github.com/stackforge/os-ansible-deployment/blob/master/playbooks/vars/repo_packages/openstack_other.yml#L40-L49

In testing I've found removing them to be an appropriate course of action because both of these now pinned items have upper boundaries set in global-requirements, which should resolve package incompatibility problems with released version of the OpenStack services.
