By default, io checker will cause Scylla to shutdown if it finds specific system errors. Right now, io checker isn't flexible enough to allow a specialized handler. For example, we don't want to Scylla to shutdown if there's an permission problem when uploading new files from upload dir. This desired flexibility is made possible here by allowing a handler parameter to io check functions and also changing existing code to take advantage of it. That's a step towards fixing #1709.
