var LifecycleNameMap = map[string]Lifecycle{
	"Sync":                     LifecycleSync,
	"Ignore":                   LifecycleIgnore,
	"WarnIfInsufficientAccess": LifecycleWarnIfInsufficientAccess,
	"ExistsAndValidates":       LifecycleExistsAndValidates,
	"ExistsAndWarnIfChanges":   LifecycleExistsAndWarnIfChanges,
}

LifecycleNameMap is used to validate in the UX. When a user provides a lifecycle name it then can be mapped to the actual lifecycle.

Lifecycles are used for ux validation. When validation fails the lifecycle names are printed out.

func BuildChanges

func BuildChanges(a, e, changes interface{}) bool
