The AdminQ handler has an error handler that automatically prints an error message when the request has failed. However, there are situations where the caller can expect that it might fail and has an alternative strategy, thus may not want the error message sent to the log, such as hitting -ENOSPC when adding a new vlan id. We add a new interface to the AdminQ API to allow for override of the default behavior, and an interface to the use standard error message formatting.
