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.
