replace the native quickstart inventory with github.com/redhat-openstack/ansible-role-tripleo-inventory

[wes hayutin]

Inventory is a core feature of a virt provisioning tool.
ATM, quickstart is pulling in github.com/redhat-openstack/ansible-role-tripleo-inventory via requirements. A suggestion was made to move art-inventory directly into quickstart itself and remove the native inventory code.

[John Trowbridge (trown)]

Yep, it is a bit odd to be pulling this fundamental functionality from out of tree.

    Replace the native quickstart inventory with ansible-role-tripleo-inventory

    - Inventory is a core feature of a virt provisioning tool. At the
    moment, quickstart is pulling in art-inventory [1] via requirements.txt.
    This patch is dumping art-inventory [1] directly into quickstart itself.
    - Convert roles/tripleo-inventory/README.md in rst format.
    - Remove some extra newlines at end of file.
    - Remove unnecessary files and directory.
