Describe the issue
Generate Master Encryption Key and File task has no error handling

To Reproduce
If the confluent_cli_path is undefined, or the cli package wasn't installed correctly, the
/bin/sh: line 1: {{ confluent_cli_path }}: No such file or directory", appears on the stderr, but the task doesn't fail.

Expected behaviour
Later, the Copy Security File Back to Ansible Host task fails, but it should fail right away.
