Move base job to project-config

This needs to be a trusted job because of the way we are performing
log copying.  Move it to this repo, which is trusted.

+      The base job for OpenStack's installation of Zuul.
+
+      All jobs ultimately inherit from this.  It runs a pre-playbook
+      which copies all of the job's prepared git repos on to all of
+      the nodes in the nodeset.  It runs a post-playbook which copies
+      all of the files in the logs/ directory of every node on to the
+      logserver.
+
+      It also sets default timeout and nodeset values (which may be
+      overidden).
