[PATCH v2 00/17] Various improvements to the testsuite

["'Felix Moessbauer' via isar-users" <isar-users@googlegroups.com>]

This series aims at simplifying and speeding up the testsuite execution.
This should enable contributors to actually run it and test their patches.

As pointed out in [1], the testsuite currently tests various features over
and over again, while others are not tested at all. We try to improve this
by focusing on "feature" tests, whereby each test case checks a set of
features instead of a whole image. We further identified long running tasks
(like the kernel builds) and move them to a dedicated test.

The execution time reduction varies greatly depending on the hardware,
network and sstate usage. When applying these changes on recently added
patches, the time was often decreased by more than 50% on "fast".

Note, that more refactorings of the testsuite are needed - and planned,
but this series should already address the biggest pain points.

Changes since v1:

- continued work on testsuite refactoring, this supersedes:
  - testsuite: fix SignatureTest by avoiding absolute path in bblayers
  - testsuite: add rootfs target for rootfs only tests
  - Enable SState cache in GitLab CI
  - testsuite: fix typo in log message in perform_signature_lint
- completed exclusion / refactoring of db2m sbuild chroot
- GitLab CI: increased after script timeout to give sstate upload more time
- GitLab CI: do not upload sstate artifacts of images (as almost no reuse)
- do not add SignatureTest to fast tag (as otherwise VM tests break...)
- rebuild container test images in VM test to not depend on test order
- rebased onto next

As always, the patches are written in a linear way, so only parts of them
can already be integrated.

That's a wrap for this year, isar developers!
See you next year!
