Improve mkfs options

- make quiet
- force, so some adjustments are not checked see https://github.com/docker/pinata/issues/6198
- set resize_inode as we do resize partitions on cloud and they could have very few inodes otherwise
- inline all the default options and remove the config file, so script is more standalone
