Currently we have IOPs of these patterns ``` [OS] os.Mkdir play.min.io:9000 /disk1 2.718µs [OS] os.Mkdir play.min.io:9000 /disk1/data 2.406µs [OS] os.Mkdir play.min.io:9000 /disk1/data/.minio.sys 4.068µs [OS] os.Mkdir play.min.io:9000 /disk1/data/.minio.sys/tmp 2.843µs [OS] os.Mkdir play.min.io:9000 /disk1/data/.minio.sys/tmp/d89c8ceb-f8d1-4cc6-b483-280f87c4719f 20.152µs ``` It can be seen that we can save quite Nx levels such as if your drive is mounted at `/disk1/minio` you can simply skip sending an `Mkdir /disk1/` and `Mkdir /disk1/minio`. Since they are expected to exist already, this PR adds a way for us to ignore all paths upto the mount or a directory which ever has been provided to MinIO setup.
