docs: Get all singularity requests that their state is either ACTIVE, PAUSED or COOLDOWN
  
  For the requests that are pending to become ACTIVE use:
  {@link SingularityClient#getPendingSingularityRequests()}
  
  For the requests that are cleaning up use:
  {@link SingularityClient#getCleanupSingularityRequests()}
  
  
  Use {@link SingularityClient#getActiveSingularityRequests()}, {@link SingularityClient#getPausedSingularityRequests()},
  {@link SingularityClient#getCoolDownSingularityRequests()} respectively to get only the ACTIVE, PAUSED or COOLDOWN requests.
  
  @return
  returns all the [ACTIVE, PAUSED, COOLDOWN] {@link SingularityRequestParent} instances.
