Set LOGNAME env var to fix Ansible logging
Set LOGNAME env var to fix Ansible logging

The getpass.getuser() method, used by the Ansible logging file, can
incorrectly report the user as it checks a list of environment
variables in order to get the user name. Under some circumstances,
e.g., daemons, you may not get the correct username because LOGNAME
will not get set correctly.
