Extract vault related bits of DataLoader._get_file_contents to DataLoader._decrypt_if_vault_data When loading vault password files, detect if they are vault encrypted, and if so, try to decrypt with any already known vault secrets. This implements the 'Allow vault password files to be vault encrypted' (#31002) feature card from the 2.5.0 project at https://github.com/ansible/ansible/projects/9 Fixes #31002
