Salt 3000.3, apache.signal graceful returns error

Description of Issue

On Salt 3000.3, running 'apache.signal graceful' returns:

Passing arguments to httpd using apachectl is no longer supported.
You can only start/stop/restart httpd using this script.
If you want to pass extra arguments to httpd, edit the
/etc/sysconfig/httpd config file.

Running 'apache.signal configtest' returns the expected "Syntax OK" message.

Steps to Reproduce Issue

[master ~]# salt 'minion' apache.signal configtest
minion:
    Syntax OK
[master ~]# salt 'minion' apache.signal graceful
minion:
    Passing arguments to httpd using apachectl is no longer supported.
    You can only start/stop/restart httpd using this script.

Start by reproducing the apache.signal graceful entry point on Salt 3000.3 with Apache on CentOS 7, then inspect how graceful arguments are passed compared with configtest. Done means apache.signal graceful completes successfully without the apachectl argument error while configtest still returns Syntax OK.
