Changes in this release:

Commit	Change
1a267ab	@arikkfir: add "--skip-gdm" and "--skip-project-setup" flags: - the "--skip-gdm" flag will make deployster skip Google Deployment Manager deployments - the "--skip-project-setup" will make deployster assume that the project exists, and has already been set up (permissions, billing, APIs, etc)
1d724a7	@arikkfir: reorder instructions in Dockerfile to first install dependencies and after that add our files; logic is that if source code changes, no need to invalidate the layers with our dependencies.
36e67f7	@arikkfir: remove support for the 'kubernetes/security' (move it to 'kube-system') and expect 'kube-system' resources in the 'kube-system' directory (no more just 'system'...)
