Subject: [PATCH] Change the default Pod CIDR to 10.20.0.0/14

* Change the default Pod CIDR from 10.2.0.0/16 to 10.20.0.0/14
(10.20.0.0 - 10.23.255.255) to support 1024 nodes by default
* Most CNI providers divide the Pod CIDR so that each node has
a /24 to allocate to local pods (256). The previous `10.2.0.0/16`
default only fits 256 /24's so 256 nodes were supported without
customizing the pod_cidr
