Fix race condition for /openstack directories

To resolve a possible race condition when containers are creating
log directories the /openstack directory and its basic sub-directories
are being created within the openstack_hosts role which will ensure that
the appropriate skeleton is available when the containers go to build
in subsequent tasks.
