[DRBD-user] drbd-reactor v0.8.0-rc.1

[Roland Kammerer]

Dear DRBD Reactor users,

this is RC1 of the upcoming drbd-reactor v0.8.0 release. The main change
is integration of "secondary --force" in the promoter plugin. IMO that
is a very nice feature and can make the difference between rebooting a
node hat has hundreds of resources just because of one faulty service
and handling that scenario more benign, even recovering from an isolated
Primary.

There is a blog post that goes into more details here [1].

Please test, using secondary-force will be the new default for v0.8.0,
no configuration changes necessary. Old behavior can be restored by
setting "secondary-force = false" in a promoter section. This requires a
kernel module >= 9.1.7 and drbd-utils >= 9.21.2

If there are no complaints I will release the final version in about a
week from now.

Regards, rck

Changelog:
* CI: update for gitlab 15.0
* prometheus: expose force-io-failures
* doc: typo fix
* promoter: implement secondary --force
* bump min versions for secondary --force
* core: mv version checks to main
