rspconfig setting hostname broken for last 2 day (PR #4326)

[whowutwut]

Running my UT autoamtion, I find that setting hostname is broken, caused by #4326.....

It looks like the endpoint got deleted in the last code changes to rspconfig... ..

The UT scripts work and show the correct HostName endpoint.

[root@briggs01 Network]# ./set_hostname.sh f6u18-bmc

  "message": "200 OK",

Automation UT Testcases added with #4379

[gurevichmark]

Fixed by PR #4380
Seems that #4326 removed the url path for hostname setting of /config/attr/HostName

Closing this issue out, if we do not see it occur on automation #4370, then should be fixed.
