Add migrate command for legacy HPAs

There are current broken HPAs floating around that either use the legacy
oapi DeploymentConfig defintion (`v1.DeploymentConfig`) or the incorrect
API group, due to the webconsole (all scalables, but with the group as
`extensions/v1beta1`).  This introduces a migrate command that corrects
the ScaleTargetRef of those HPAs to have correct API groups that are
usable by generic scale clients.
