8c4379862a rebase: remove "github.com/pkg/errors" from go.mod
There is no direct dependency on "github.com/pkg/errors" anymore, so it
can be removed from go.mod.

After running `go mod tidy`, the "github.com/pkg/errors" gets downgraded
to a version that is referenced in other depndencies. This was
unexpected, but seems needed.

25e3a961c3 rbdplugin: idempotent DeleteVolume
When the initial DeleteVolume times out (as it does on slow clusters
due to the low 10 second limit), the external-provisioner calls it
again. The CSI standard requires the second call to succeed if the
volume has been deleted in the meantime. This didn't work because
DeleteVolume returned an error when failing to find the volume info
file:

  rbdplugin: E1008 08:05:35.631783       1 utils.go:100] GRPC error: rbd: open err /var/lib/kubelet/plugins/csi-rbdplugin/controller/csi-rbd-622a252c-cad0-11e8-9112-deadbeef0101.json/open /var/lib/kubelet/plugins/csi-rbdplugin/controller/csi-rbd-622a252c-cad0-11e8-9112-deadbeef0101.json: no such file or directory

The fix is to treat a missing volume info file as "volume already
deleted" and return success. To detect this, the original os error
must be wrapped, otherwise the caller of loadVolInfo cannot determine
the root cause.

Note that further work may be needed to make the driver really
resilient, for example there are probably concurrency issues.
But for now this fixes: #82
