* Add ability to append suffix to host names for Cloudforms Inventory
Allows for use of a suffix that will be appended to host names returned
from Cloudforms API if that suffix is not present.
For example with a suffix of 'example.org', the following results
would be shown for a particular Cloudforms host name:
someexample -> someexample.example.org
someexample.example.org -> someexample.example.org
The main use-case for this is when Cloudforms has short names rather
than FQDN and there is a desire to to use the FQDN as the name.
* Add example line into Cloudforms INI file
* Clarify that leading fullstop needed
* Add validation to ensure leading fullstop for suffix
