Extend the mount manager to support more transformers than format. The transformers allow altering the mount before it is passed to the mount handlers. These could be one-time actions which are needed to perform the mount. Adds mkdir and mkfs actions which can be used to prepare the arguments for a mount. The actions can be limited to actions within the target mount directory or plugin directories. Signed-off-by: Derek McGowan <derek@mcg.dev>
