Destroys a secret version's data.
googlesecrets.destroyVersion(secretName, versionId, [callback])
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
This method permanently destroys the secret data held by the secret version specified by SecretName and VersionId. The secret version itself remains in existence, but its SecretState changes to DESTROYED and attempting to call GetSecret on it will result in an error.
To make a secret version's data temporarily inaccessible, use the SetVersionEnabled method instead.
