> When placeholders allocation are released with terminationType
> `si.TerminationType_TIMEOUT`. The reason could be one of the following:
> # "releasing allocated placeholders on placeholder timeout"
> ([Link-1|https://github.com/apache/yunikorn-core/blob/21303191a9c9ee791de3371ddca973df51b7a755/pkg/scheduler/objects/application.go#L434])

> # "releasing placeholders on app complete"
> ([Link|https://github.com/apache/yunikorn-core/blob/21303191a9c9ee791de3371ddca973df51b7a755/pkg/scheduler/objects/application.go#L360])
> # “cancel placeholder: resource incompatible”
> ([Link|https://github.com/apache/yunikorn-core/blob/21303191a9c9ee791de3371ddca973df51b7a755/pkg/scheduler/objects/application.go#L1148])
> Those reasons are encapsulated in
> *si.AllocationResponse([Link|https://github.com/apache/yunikorn-core/blob/21303191a9c9ee791de3371ddca973df51b7a755/pkg/scheduler/context.go#L901])
> and passes to shim. However, the shim doesn’t expose them, it simply logs an
> event to the originator pod with a generic reason
> ([Link|https://github.com/apache/yunikorn-k8shim/blob/f2819084f8720aa0eec8e1f41a886413b22d93b2/pkg/cache/application.go#L695-L696]):
> * Type: Warning
> * Reason: GangScheduling
> * Message: Application XXXXXX placeholder has been timed out
> We could consider to expose the true reason to originator pod. Ex: (In
> originator pod.)
> * Type: Warning
> * Reason: GangScheduling
> * Message: placeholder xxx has been released. (reason: cancel placeholder:
> resource incompatible)
