The type of update process. You can specify either PROACTIVE so that the instance group manager proactively executes actions in order to bring instances to their target versions or OPPORTUNISTIC so that no action is proactively executed but the update will be performed as part of other actions (for example, resizes or recreateInstances calls).
Additional supported values which may be not listed in the enum directly due to technical reasons:
PROACTIVE
No action is being proactively performed in order to bring this IGM to its target version distribution (regardless of whether this distribution is expressed using instanceTemplate or versions field).
UndefinedType
A value indicating that the enum field is not set.
