[PATCH 00/23] remove old kernel-ci and enhance reboot-limit

[Luis Chamberlain <mcgrof@kernel.org>]

The CONFIG_KERNEL_CI thing was used back in the hay day before we
adopted fstests SOAK_DURATION. Although CONFIG_KERNEL_CI proved useful
to test fstests in a loop -- the only reasonable way to scale is to just
embrace SOAK_DURATION and extend any twitches we need within fstests.

However only one workflow uses CONFIG_KERNEL_CI still. So move that
functionality directly into the reboot-limit workflow which uses it.
While at it, as a drive by, let's enhance the reboot limit workflow with
kexec and also graphing capabilities allowing us to do A/B testing for
reboots and kexec regression testings.

The rationale for this work si to help fix any misunderatandings on what
kdevops's kernel CI support consists of, and CONFIG_KERNEL_CI certainly
was not it. It's evolved now to just the kdevops kernel-ci repo and the
the .ci/ symlinks, along with optional kernel-kpd trees for subsystems.
