Ticket 48450 - Add prestart work around for systemd ask password
Bug Description: Due to a lack of response to fix the systemd ask password
permissions, we must resolve this ourselves. Without this, we cannot utilise
the ask password feature at all.
Fix Description: We add an execstartpre script, that parses dse.ldif for
the running server user. If found, we add the acl to ask-password directory
which will allow the server to start. We do this so that if each instance
has a unique user, they can all use ask pass correctly.
