Bug 1807532

Description of problem: While creating hostgroup through hammer getting error: 
~~~
Could not create the hostgroup:
  Error: hostgroup not found.
~~~

Creating the child hostgroup through WEB UI works as it gives the option to select the complete Parent hostgroup path. However from hammer we cannot select the complete Parent hostgroup path.

For example:
~~~
[root@sat ~]# hammer hostgroup create --organization RedHat --name 20c --parent new1/latest/abcd
Could not create the hostgroup:
  Error: hostgroup not found.
~~~

While, we can create a child hostgroup by only mentioning abcd:
~~~
[root@sat ~]# hammer hostgroup create --organization RedHat --name 20c --parent abcd
~~~

This becomes a problem if we have multiple parent hostgroup paths with same names. For example:

Version-Release number of selected component (if applicable):
