Complete GCE integration

[lmercl]

Hello,
looks like kubespray doesn't have finished integration to GCE.

Basically there is needed 2 things:

1. creating PVs - already done by csi-gce-pd-controller,
2. creating LB resources - not finished - not working with current kubespray code

Creating LB resources
My deployed stack has set cloud_provider: gce, and it works for PVs (with good config), but LBs are not working. Basically I'm able to resolved with editing /etc/kubernetes/manifests/kube-controller-manager.yaml by adding two the new params:

    - --cloud-provider=gce
    - --cloud-config=/etc/kubernetes/cloud-config

This can be resolved by adding gce to this (and similar) IFs:

kubespray/roles/kubernetes/control-plane/templates/kubeadm-config.v1beta2.yaml.j2

Line 200 in a0ee569

{% if cloud_provider is defined and cloud_provider in ["openstack", "azure", "vsphere", "aws"] %}

Basically it's only add cloud-provider options to GCE and create file with configs.
I'm not sure if there will be some more integration needed, but not working LBs can be resolved only by this.

Thanks for the issue, maybe open up a PR with that ?
I guess you have to change at least all checks in kubeadm-config.v1beta2.yaml (L200/217?/219/293/310/317)

And maybe

kubespray/roles/kubernetes/node/templates/kubelet.env.v1beta1.j2

Line 46 in 65540c5

{% if cloud_provider is defined and cloud_provider in ["openstack", "azure", "vsphere", "aws", "external"] %}
