Ticket 49390, 50019 - support cn=config compare operations
    
    Bug Description: Ansible will attempt to check the state of a value
    before it makes an alteration on the ldap server. To do this in a
    correct and schema aware fashion, it will use the ldapcompare operation.
    
    It's a request that people want to manage their cn=config with ansible,
    however dse.c didn't support ldapcompare on these backends.
    
    Fix Description: Add support for ldapcompare operations on dse.c,
    including the ability to correctly generate the cn=config defaults
    into the entry for comparison.
    
    This also adds support for ldapcompare as the default comparitor in
    lib389.
