Please update vendored copy of k8s.io/client-go

[dholbach]

Our current copy of k8s.io/client-go uses juju/ratelimit which is LGPL3. Upstream moved away from this in kubernetes/client-go@acc5249 - it'd be good if we followed this change as well.

(This was solved in weave in weaveworks/weave#3366 as well.)

This will get fixed once #898 is merged

[dholbach]

Brilliant - thanks for the update @csmarchbanks!

Fixed by #898
