Improve cni windows code

[manuelbuil]

Proposed Changes

This PR does a few things:
1 - Fixes a bug in calico which prevented pods from starting (config should have "Calico" instead of "calico")
2 - Increases time out to 30s. I saw twice during my tests that sometimes 20s is not enough for the interfaces to come back in Windows
3 - Similarly to Flannel, before starting Calico, we check if the node is present in kube-api to avoid potential issues
4 - Instead of using an infinite loop to start calico, we use wait.PollImmediateWithContext with a time out of 5 minutes
5 - Flannel's wait.PollImmediateWithContext now return an error
