Adding the caching you'd put a TODO on in r84298 and r84300

Set for 24 hours, don't know if you want longer.

Only other tweak is maybe making keys more unique.

$key = wfMemcKey( 'openstackmanager', 'domaininfo', $this->domainname );

Add it before the last parmameter, not sure if you need any more uniqueness

More adding this as a TODO as you've gone offline ;)
