Subject: [PATCH] Make kubevirt's CPU allocation ratio configurable

Kubevirt's default cpu-to-vcpu ration is 1:10, which might be a bit
extreme for some users. This patch introduces a new key in the Cozystack
configmap, "cpu-allocation-ratio" where admins of Cozystack can specify
an alternative value, if needed.
