Clashing VPA dependencies between etcd-druid and gardener/gardener

What happened:
As a developer, I work on both etcd-druid as well as gardener/gardener on my local machine. With the latest change in druid from #748 , the vendor folder is removed, and dependencies are vendored to the go mod cache. Since master branch of g/g uses dependency k8s.io/autoscaler/vertical-pod-autoscaler v1.0.0 and etcd-druid uses indirect dependency k8s.io/autoscaler v0.0.0-20190805135949-100e91ba756e // indirect from an older version of g/g, there seems to be an issue with my GoLand IDE in resolving the correct vpa dependency for g/g. Instead of using k8s.io/autoscaler/[email protected] from the go mod cache, it seems to be resolving to k8s.io/autoscaler v0.0.0-20190805135949-100e91ba756e/vertical-pod-autoscaler by default, which causes linter errors for g/g.

I would like to bring the indirect vpa dependency in etcd-druid to the same version as the g/g dependnecy it vendors, ie, k8s.io/autoscaler/vertical-pod-autoscaler v1.0.0.

How to reproduce it (as minimally and precisely as possible):
Checkout current etcd-druid master and g/g master and run make tidy on both.
