Revert "IKEv1 XAuth: Temporarilty add an "initiate_later" flag to the task manager. When set to TRUE it will cause "initiate" to be called when the current process_response call is finished. This change should be reverted once we have a better method in place."

This reverts commit c6c28f4ac522dd8afb457847bca79eee77f78706.

Revert "IKEv1 XAuth: Added temporary "initiate_xauth" public method to ike_sa_t.  This allows us to initiate an XAuth password authentication exchange after responding to the final message of Main Mode.  This change should be reverted once we have a better method to initiate this exchange."

This reverts commit 5529dc50477e25df9dd5f3c442bb1521c0baf225.
