build: move some of hack/lib/ into a new cluster/lib/

Some functionality in hack/lib is currently depended on by
cluster/common.sh so kube-up from the full release tar (which
does not include hack/) is currently broken. With this PR we
create cluster/lib/ and move the necessary bits from hack/
over to get kube-up working again.
