The test tries to bind configured nr. of PVs to the same nr. of PVCs.
'100' is used by default, which should take ~1-3 seconds (depends on log level).
Periodic sync is needed in rare cases, which may add another 10 seconds. - cache
from #25881 will help here and sync should not be needed at all.
The test is configurable and may be reused to measure binder performance.
Set KUBE_INTEGRATION_PV_* env. variables as described in
persistent_volume_test.go and run the tests:
# compile
$ cd test/integration
$ godep go test -tags 'integration no-docker' -c
# run the tests
$ KUBE_INTEGRATION_PV_SYNC_PERIOD=10s KUBE_INTEGRATION_PV_OBJECTS=1000 time ./integration.test -test.run TestPersistentVolumeMultiPVsPVCs -v 2
Log level '2' is useful to get timestamps of various events like
'TestPersistentVolumeMultiPVsPVCs: start' and 'TestPersistentVolumeMultiPVsPVCs:
claims are bound'.

Stabilize persistent volume integration tests
- add more logs
- wait both for volume and claim to get bound
When binding volumes to claims the controller saves PV first and PVC right
after that. In theory, this saved PV could cause waitForPersistentVolumePhase
to finish and PVC could be checked in the test before the controller saves it.
So, wait for both PVC and PV to get bound and check the results only after
that. This is only a theory, there are no usable logs in integration tests.
Fixes#26499 (at least I hope so...)

Don't allow deps with no discernible license
This updates the few deps we had with no LICENSE file to current versions that do have that file. It also disallows new deps without obvious licenses.

Disable PodAffinity SchedulerPredicates test
This feature is disabled, so it's not surprising that tests don't work.

@david-mcmahon - this disables the second test that causes failures in SchedulerPredicates suite. When this and #26695 are merged it should be passing in serial.

Revert revert of adding resource constraints for master components in density tests

Add direct serializer
Fix#25589. Implemented a direct codec that doesn't do conversion, but sets the group, version and kind before serialization as Clayton suggested [here](https://github.com/kubernetes/kubernetes/issues/25589#issuecomment-219168009).
First commit is cherry-picked from #24826.

SSH e2e: Limit to 100 nodes, limit combinatorics
[]()This limits the "for all hosts" to 100 nodes, and also limits the
combinatorial section so that we only do the other SSH command variant
testing on the first host rather than *all* of the hosts. I also
killed one of the variants because it didn't seem to be testing much
important.
Fixes#26600

- Exit non-0 if infrastructure failures happen
- Exit 0 if no infrastructure failures happen regardless of test results

Use pause image depending on the server's platform when testing
Removed all pause image constant strings, now the pause image is chosen by arch. Part of the effort of making e2e arch-agnostic.
The pause image name and version is also now only in two places, and it's documented to bump both
Also removed "amd64" constants in the code. Such constants should be replaced by `runtime.GOARCH` or by looking up the server platform
