[stable/consul] Consul 1.0.0 (#2724)
* Update consul image to 1.0.0 This fixes a lot of the stability issues on k8s * Add pod anti affinity to spec This ensures a single node failure doesn't take out multiple consul services * Use the rolling update strategy for updates * Add a pod disruption budget * Bump chart version * Update README to reflect ImageTag update * Make anti-affinity settings configurable in Values.yaml * Bump [stable/consul] to 1.0.0
