Make root-only information clear in sysadmin.rst.

As we document more fully, it has become clear that the sysadmin page
really has two audiences: openstack-ci contributors and
openstack-ci/cloned-infra root operators.

Add a pointer to launch/README for root operators.

Cause it's not discoverable at the moment.

Start documenting running your own CI infra.

This is incomplete, but as I haven't got a full thing up yet I can't
write it all. It is minimally a useful pointer for other folk trying
to do the same thing.

Make setting up a Puppetmaster easier.

There is a helpful script we can use that avoids the plumbing
discussion, and neither raring nor F19 can run a Puppet master, so we
should document that to avoid false starts.

Document bootstrapping a new infrastructure.

Change-Id: Ic3345ecfe1c093ef68844430ed1c77cadbcf8b94
Port across params and puppet_cron.

The bottom of the dependency stack.

Initial bootstrap configuration.

Just enough to get a puppetmaster up, I hope.
