The most disruptive action that you want to perform on each
instance during the update: - REPLACE: Delete the instance and
create it again. - RESTART: Stop the instance and start it
again. - REFRESH: Do not stop the instance and limit disruption
as much as possible. - NONE: Do not disrupt the instance at all.
By default, the most disruptive allowed action is REPLACE. If
your update requires a more disruptive action than you set with
this flag, the update request will fail. Additional supported
values which may be not listed in the enum directly due to
technical reasons:
