the element root. This fixes failing builds of heat-cfntools.

remove use-config-templates from cinder-config:

use-config-templates has been deprecated, and must
not be used by the cinder element.

This change relies on os-refresh-config instead.

TO PROPOSE: Touch a first-boot.status file:

After running first-boots scripts, both to indicate
that the scripts have completed, and also to record
the exit status.

This is useful for automated testing:
  - tests can wait until first-boot scripts have
    completed before commencing testing
  - tests can abort further testing if first-boot
    scripts have failed.

Replace glance-api+glance-reg elements with glance:

'glance' element now results in a properly-configured,
working glance service on first boot.

While glance-api and glance-reg may need to be broken
out again in the future, the intention now is to focus
on a working service for an end-to-end PoC.

remove database-initialization from openstack-db:

Database initialization is different for bootstrap node,
vs. first baremetal database node, so database init,
should happen outside the openstack-db element.
