Cherry pick of #81 on release-0.9.

#81: connection: exit with less output on connection loss

Part of kubernetes-csi/external-provisioner#732

Does this PR introduce a user-facing change?:

sidecars exit without output about goroutines when losing the connection to the driver

For details on the cherry pick process, see the cherry pick requests page.

@pohly @ialidzhikov
connection: exit with less output on connection loss
29f418d 
klog.Fatal dumps information about all running goroutines when the
connection to the CSI driver is lost. Loosing the connection is normal
and depends on the order in which containers are shut down. If it
happens, then the reason is unlikely to be related to goroutines.

Therefore this extra output is not helpful or worse, fills up logfiles
when a sidecar has many goroutines, as in the external-provisioner
which runs 100 workers by default.

Hi @ialidzhikov. Thanks for your PR.

I'm waiting for a kubernetes-csi member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

I wonder whether we really need to fork csi-lib-utils.

Can we update the older external-provisioner branches to the latest csi-lib-utils instead?

Can we update the older external-provisioner branches to the latest csi-lib-utils instead?

Sure, this is also an option. I was not sure how backwards-compatible is updating minor versions of this library from 1 patch version to another one for a sidecar (for example external-provisioner). That's why the safer approach to me is to have v0.9.2 with this concrete patch. WDYT?

I looked at the changes in csi-lib-utils 0.10 and 0.11 and I think those are safe all the way back to release-2.1.

@pohly I quickly tried out. In short github.com/kubernetes-csi/[email protected] has its K8s dependencies updated to v0.22.0. Trying to vendor github.com/kubernetes-csi/[email protected] in [email protected] does a lot of changes under vendor:

$ git diff --shortstat
 193 files changed, 1923 insertions(+), 4620 deletions(-)

(dependencies like golang.org/x/net, golang.org/x/sys, google.golang.org/grpc get updated)

I would suggest to pick the approach with the cherry-pick and new patch release (github.com/kubernetes-csi/[email protected]). Looks cleaner and safer to me.
