APICallRetryInterval defines how long kubeadm should wait before retrying a failed API operation.

TODO: These constants should actually come from pkg/kubeapiserver/authorizer, but we can't vendor that package in now because of all the other sub-packages that would get vendored.

Constants for what we name our ServiceAccounts with limited access to the cluster in case of RBAC.

Minimum amount of nodes the Service subnet should allow.

Important: a "v"-prefix shouldn't exist here; semver doesn't allow that.
