LDAP: Add sdap_lookup_type enum

Related:
    https://fedorahosted.org/sssd/ticket/2553

Change the boolan parameter of sdap_get_users_send and sdap_get_groups_send
to a tri-state that controls whether we expect only a single entry
(ie don't use the paging control), multiple entries with a search limit
(wildcard request) or multiple entries with no limit (enumeration).
