docs: Queue a task to the global executor.
  Prereq: maxConcurrencyConstraint permit must already be acquired to reflect the task being queued to global.
  If unsuccessful in queuing to global, this method releases the maxConcurrencyConstraint permit.
  
  @param globalTask task that can execute tasks that are queued to the policy executor.
