Remove need for FortisDeployVM

[c-w]

1. Remove vm extenstion to run fortis-deploy.sh (https://github.com/CatalystCode/project-fortis-pipeline/blob/master/azuredeploy.json#L472)
2. Remove deployment VM from ARM template: https://github.com/CatalystCode/project-fortis-pipeline/blob/master/azuredeploy.json#L363
3. Define acs-engine template with an extension in the masterprofile (https://github.com/Azure/acs-engine/blob/0224c051212524b2a71e00db8cf40783fe677359/docs/extensions.md#masterprofile) to run fortis-deploy.sh on a single master: https://github.com/Azure/acs-engine/blob/0224c051212524b2a71e00db8cf40783fe677359/docs/extensions.md
4. Create ARM template using acs-engine (https://github.com/Azure/acs-engine/blob/e3b22c480c0298b2cf1dce41c4a7e87ac49f46f3/docs/kubernetes/deploy.md)
5. Switch creation of k8s cluster to use acs-engine created for k8s cluster instead of cluster resource https://github.com/CatalystCode/project-fortis-pipeline/blob/master/azuredeploy.json#L439 a. Look at nested ARM templates like I started here: https://github.com/xtophs/project-fortis-pipeline/tree/multi-dc-deploy
6. Remove az cli stuff from https://github.com/CatalystCode/project-fortis-pipeline/blob/master/fortis-deploy.sh a. Az cli is only needed to ssh to master to get kubeconfig to run kubectl b. Since you’re now running on the master, you already have kubeconfig
