Raise Kubernetes CPU requests from 10m to 50m

This setting is passed by Kubelet to the Linux scheduler to ask for a share of
available CPU, so we should ask for a bit more than 1% of 1 CPU. Otherwise if a
CPU is contended Weave Net will get throttled frequently.

Weave Net in fastdp mode shouldn't need a lot of CPU most of the time, but at
startup there is quite a lot to do.

The setting is also used by the Kubernetes scheduler to decide how much will fit
on a node, so setting it much higher will reserve CPU that we shouldn't need most
of the time.
