The referint plugin does a substring search on these attributes each time an
entry is deleted, which causes a noticable slowdown for large directories if
the attributes are not indexed.

An unindexed search for ipakrbprincipalalias is fired for every ipa
command (and other authentication events) which would degrade IPA
server performance if not indexed. ipaautomountkey unindexed searches
are hit when new key entries are being added.
Add both indexes to new and updated IPA installs.

Many attributes in IPA (e.g. manager, memberuser, managedby, ...)
are used to store DNs of linked objects in IPA (users, hosts, sudo
commands, etc.). However, when the linked objects is deleted or
renamed, the attribute pointing to it stays with the objects and
thus may create a dangling link causing issues in client software
reading the data.
Directory Server has a plugin to enforce referential integrity (RI)
by checking DEL and MODRDN operations and updating affected links.
It was already used for manager and secretary attributes and
should be expanded for the missing attributes to avoid dangling
links.
As a prerequisite, all attributes checked for RI must have pres
and eq indexes to avoid performance issues. Thus, the following
indexes are added:
* manager (pres index only)
* secretary (pres index only)
* memberHost
* memberUser
* sourcehost
* memberservice
* managedby
* memberallowcmd
* memberdenycmd
* ipasudorunas
* ipasudorunasgroup
Referential Integrity plugin is updated to enforce RI for all these
attributes. Unit tests covering RI checks for all these attributes
were added as well.
Note: this update will only fix RI on one master as RI plugin does
not check replicated operations.
