Complete fix for issue 2263.

The setup will automatically initialize the schema of the local server with the schema of the remote server.

A new argument has been added to dsreplication enable (useSecondServerAsSchemaSource) to allow the user to specify which server must be used to initialize the schema of the other.  The usage of this argument is:
Use the second server to initialize the schema of the first server.  If this option nor option {noSchemaReplication} are specified the schema of the first server will be used to initialize the schema of the second server
