Description of problem:

There is no option to search 'obfuscate_hostname=True'  system over the portal.

~~~
If you access cloud.redhat.com and browse the host inventory it will onlly show the hostname. In case of obfuscated hostnames this is not very useful. In the old insights page or on satellite insights the hosts are also showing the display name. 

Please bring the "display name" into the inventory view.

obfuscate=True

~~

2. #insights-client  --register 


Actual results:
systems get registered with 'host1.example.com' (next system would be host2.example.com ) 


Expected results:
There is no filter over the portal to find these systems.
