Foreman Maintain

I tried to restart services on a proxy. It tried to setup hammer and failed (tracked as issue #24795) and suggested to use --whitelist option.
When I followed the instructions I found out the --whitelist option does not exist.

# foreman-maintain service restart
Running preparation steps required to run the next scenarios
================================================================================
Setup hammer:                                                         [FAIL]
undefined method `[]' for nil:NilClass
--------------------------------------------------------------------------------
Scenario [preparation steps required to run the next scenarios] failed.

The following steps ended up in failing state:

  [hammer-setup]

Resolve the failed steps and rerun
the command. In case the failures are false positives,
use --whitelist="hammer-setup" 

[root@capsule-6-4-compose-rhel7 ~]# foreman-maintain service restart --whitelist="hammer-setup" 
ERROR: Unrecognised option '--whitelist'

See: 'foreman-maintain service restart --help'

Expected results:
I shouldn't be suggested to use the option that does not exist or the option should work.
