NC | NSFS | CLI | list_config_files Small Fix

[shirady]

Explain the changes

1. list_config_files change function signature (remove unused config_path), and edit JSDoc (add missing type).
2. Rename the option from should_decrypt to decrypt_secret_key as the destructor of options uses.

Issues:

1. Currently, when using list we get the encrypted_secret_key instead of secret_key.

Testing Instructions:

1. Create an account with the CLI: sudo node src/cmd/manage_nsfs account add --name shira-1001 --new_buckets_path /tmp/nsfs_root1 --access_key --secret_key --uid --gid
   Note: before creating the account need to give permission to the new_buckets_path: chmod 777 /tmp/nsfs_root1.
2. Account list with decryption: sudo node src/cmd/manage_nsfs account list --wide --show_secrets (you will see the property secret_key instead of encrypted_secret_key).

• Doc added/updated

	const data = type === TYPES.ACCOUNT ?
	await config_fs.get_account_by_name(entry.name, options) :
