code: public Optional<AlertPolicy> show(String name, long policyId)
      {
          Optional<AlertPolicy> ret = Optional.absent();
          Collection<AlertPolicy> policies = list(name);
          for(AlertPolicy policy : policies)
          {
              if(policy.getId() == policyId)
                  ret = Optional.of(policy);
          }
          return ret;
      }
docs: Returns the alert policy with the given name and id.
  <P>
  This is needed because the API does not contain an operation to get a policy using the id directly, only filtering using the name.
  @param name The name of the alert policy to return
  @param policyId The id of the alert policy to return
  @return The alert policy
