For the most part the existing replication code worked with the
following exceptions:
- Added more port options
- It assumed that initial connections were done to an SSL port. Added
ability to use startTLS
- It assumed that the name of the agreement was the same on both sides.
In dogtag one is marked as master and one as clone. A new option is
added, master, the determines which side we're working on or None
if it isn't a dogtag agreement.
- Don't set the attribute exclude list on dogtag agreements
- dogtag doesn't set a schedule by default (which is actually recommended
by 389-ds). This causes problems when doing a force-sync though so
if one is done we set a schedule to run all the time. Otherwise the
temporary schedule can't be removed (LDAP operations error).
