tegu_ha does not properly handle hostnames which do not have a domain

[ScottDaniels]

The tegu_ha.py script does not handle the case where a host name does not have an associated domain name (foo is returned instead of foo.somedom.com). The script needs properly handle this case.

Relevant trace:

2015/09/08 14:28 tegu_ha v1.1 started
Traceback (most recent call last):
