Do not save HBAC rules in subdomain subtree
Currently the sysdb context is pointed to the subdomain subtree containing user the user to be checked at the beginning of a HBAC request. As a result all HBAC rules and related data is save in the subdomain tree as well. But since the HBAC rules of the configured domain apply to all users it is sufficient to save them once in the subtree of the configured domain. Since most of the sysdb operations during a HBAC request are related to the HBAC rules and related data this patch does not change the default sysdb context but only create a special context to look up subdomain users.
