rev coreos version constraint

[2ffs2nns]

Description

The installation process in the Vagrant/Virtual box Getting-starting guide can hang downloading kubectl on older versions of coreos. After updating to current-stable the issue was resolved.

shows old/outdated coreos

  vagrant box update 
==> k8s-node-02: Checking for updates to 'coreos-stable'
    k8s-node-02: Latest installed version: 1520.8.0
    k8s-node-02: Version constraints: >= 1122.0.0
    k8s-node-02: Provider: virtualbox

after updating...

 vagrant box update
==> k8s-node-02: Checking for updates to 'coreos-stable'
    k8s-node-02: Latest installed version: 1576.4.0
    k8s-node-02: Version constraints: >= 1576.4.0
    k8s-node-02: Provider: virtualbox
==> k8s-node-02: Box 'coreos-stable' (v1576.4.0) is running the latest version.

shows I can install Calico now...

Looks like 1576.4.0 is the "latest" release.
