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 one Inventory Source is returning
names that have a FQDN name whilst others are returning a shortname, to
ensure that the hosts in an inventory aren't effectively duplicated.
