Performing Test Launch or Validate Template yields an error of "Submit action failed: 'hostname'"

[evannadeau]

Fix:
This issue has been resolved in our environment with a change to the lambda_mgn.py. Incoming PR that checks for Hostname and FQDN key in the dictionary before doing a comparison of values between CMF and MGN.

Issue:
Two servers sitting in Archive in our MGN were previously from performing an Import into MGN. However, no agents were ever installed, so Hostname and FQDN values did not exist on the servers in MGN. When trying to do a Validate Launch Template or Launch Test Instances from CMF into MGN would cause an error response of "Submit action failed: 'hostname'".
