More efficient compression

Description

Right now we use gz but xz has significantly lower file size AND much faster decompression.
Furthermore, Google has a new compression format called Brotli which could also be a good candidate.

Acceptance criteria

  • Propose alternatives to gz and measure their performance tradeoffs in various configuration

    • Key criteria: File size of a rootfs of about 500 MB and decompression resource use (including time)

  • Implement alternative as replacement for gz

The final upgrade of deployments service is here, which contains the lzma changes. I'm considering this task done, since the merging of that PR is already tracked in https://northerntech.atlassian.net/browse/MEN-2000#icft=MEN-2000, and it is a blocker for the next version.

It's private I'm afraid. Too many private credentials in the build logs that are hard to hide.
