In some occasions the node status (capacity) takes a lot of time to
update. Increase the timeout on extended resource tests. Revert the default
timeout back to 10s.
This patch addresses issues with slow node status (extended resources)
updates. Previously we did just a few retries in quick succession which
could result in the node update failing, just because node status was
updated slower than our retry window. The patch mitigates the issue by
increasing the number of tries to 15. In addition, it creates a
ratelimiter with a longer per-item (per-node) base delay.
The patch also fixes the e2e-tests to expose the issue.
Implement a new generic type nodeListPropertyMatcher, a generic Gomega
matcher for matching basically any property of a set of node objects. We
will be using it for verifying labels, annotations, extended resources
and taints for now. This moves the tests in a more Gomega'ish direction,
leveraging code re-use and providing way more informative error messages
in case of test failures.
The patch adds a new eventuallyNonControlPlaneNodes helper assertion for
asserting all (non-control-plane) nodes in the cluster, intended to
replace the ugly simplePoll() helper function.
This patch implements a matcher for node labels and converts tests to
use it instead of the old checkForNodeLabels helper function.
