support update strategy in manifestwork (#139)
* Add ssa strategy Signed-off-by: Jian Qiu <jqiu@redhat.com> * Add test cases Signed-off-by: Jian Qiu <jqiu@redhat.com> * Resolve comments Signed-off-by: Jian Qiu <jqiu@redhat.com> * Use default manager in api repo Signed-off-by: Jian Qiu <jqiu@redhat.com> * Refatcor deleteOption patch ownerref separately for deleteOption Signed-off-by: Jian Qiu <jqiu@redhat.com> * Do not reconcile when ssa conflict Signed-off-by: Jian Qiu <jqiu@redhat.com>
