Feature Request: Support executable vault-password-file

[tonyskidmore]

Hi,

Great work, this is exactly what I was looking for so thanks!

With ansible if you specify --vault-password-file or export ANSIBLE_VAULT_PASSWORD_FILE and make the file executable it will execute the file rather than read its contents. This is very handy for having a script retrieve a password for you. Would that be a feature that could be easily implemented?
