docstring: Delete a key from the settings for a particular client. Returns a boolean
  indicating whether the key existed. This does not modify the application-
  wide default value for a key.
  
  @param string $key The key to delete from the client settings. To find out
  the values available, use the 'settings/keys' API call
  first.
  
  @param string $forClientId The client identifier whose key will be deleted
  If you do not enter a value for this parameter,
  it defaults to the value of the `client_id`. In
  this case, you will delete the key from your
  own account.
