Adds a new REST service /admin/regioninfo/ --- will return a

comprehensive list of all regions in one go (in contrast to the
/admin/regions/ REST call).

Example:
% curl http://127.0.0.1:9000/admin/regioninfo/

<regions max="10" number="1">
  <region avatars="0"
          external_hostname="127.0.0.1" ip="0.0.0.0:9000"
	  master_name="Mr X" master_uuid="b757d5f9-7b36-4dda-8388-6e03dd59b326"
	  name="London" objects="6" uuid="49253666-a42e-4f44-9026-d23f93af31d7" x="1000" y="1000"/>
</regions>
