HBAC test optional sourcehost option

New version of SSSD begins ignoring sourcehost value of HBAC rules by
default. In order to match this behaviour the sourcehost option in
hbactest is optional now, but the value of sourcehost is ignored in all
rules. Every rule's sourcehost value is set to 'ALL' what turns sourchost
value comparation off. If srchost option is used, warning is displayed to
inform the user about changes. Text of plugin help was also updated.

Also the unit tests for hbactest plugin were updated. Every test was
doubled. The second ones test the plugin without sourcehost option. They
are supposed to have the same result.
