Description
K8s 1.15 introduces the reinvocationPolicy in the MWC and VWC allowing the webhook to be re-evaluated during a single admission request. This will ensure defaults defined by certain admission controllers like PodSecurityPolicy and LimitRanger are automatically added to the Linkerd proxy and proxy-init containers.
We should update the MWC template to include this property with the value IfNeeded, so that K8s 1.15+ users can take advantage of it.
