This change uses admin-node in the quick-common.rst file, including
the graph. This name is already used in
quick-ceph-deploy.rst.

The graph in quick-ceph-deploy.rst applies to
quick-start-preflight.rst.
The graph in deploy seems more complete, so I put the common
documentation in quick-common.rst and had it included.
doc/conf.py has 'start/quick-common.rst' in exclude patterns so that
sphinx does not complain about this file not being in toc.
