upgrade all dependencies
The dependabot does not update dependencies when they do not use a tag. This patch upgrades all untagged depenencies if possible. You can upgrade all dependencies with `go get -u ./... && make vendor` in theory however this failed since the k8s changes do not compile on go v1.16 so I only updated the other dependencies.
