Include calls to `df -i` (inode counts) and `df -m` (megabytes data) in validate-host, to aid in troubleshooting build failures where the builds start out with too little free space. This way the initial capacity and utilization of all available filesystems will be recorded with other basic node diagnostic data. Change-Id: Iba195e7c5cec372c6ba4daf7059da5b6fb6740ec
