Fix print_hostnames of inventory.py (#8554)
When trying to run print_hostnames of inventory.py, it outputs the following error: $ CONFIG_FILE=./test-hosts.yaml python3 ./inventory.py print_hostnames Traceback (most recent call last): File "./inventory.py", line 472, in <module> sys.exit(main()) File "./inventory.py", line 467, in main KubesprayInventory(argv, CONFIG_FILE) File "./inventory.py", line 92, in __init__ self.parse_command(changed_hosts[0], changed_hosts[1:]) File "./inventory.py", line 415, in parse_command self.print_hostnames() File "./inventory.py", line 455, in print_hostnames print(' '.join(self.yaml_config['all']['hosts'].keys())) KeyError: 'all' because it is missed to load a hosts config file before printing hostnames. This fixes the issue.
