acl: perform the ACL-as-a-service user registrations in global heap
Some users tend to call registration routine long before they need that service - which triggers an immediate initialization of the ACL heap, which is rather big. This commit defers this process by keeping the registrations in the global heap. Change-Id: I5825871bd836851942b55184b6ee2657c7a9cc33 Type: fix Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>
