'mz' can be safely replaced with fs.promises and util.promisify for faster native methods. 'mkdirp' after Node v8 uses native fs.mkdir, thus is redundant. 'body-parser' is deprecated and contained within express v4.x. Closes: #1567 Change-type: patch Signed-off-by: Christina Wang <christina@balena.io>
