Upgrade of kuma-dp on Universal should be available without downtime
Description
Upgrade of kuma-dp requires a restart of the sidecar. That can cause downtime which can cause a lot of requests to fail. We should allow users a smooth upgrade from version to version without downtime if possible. Currently, upgrades require uninstalling transparent proxy and downloading new binaries. Maybe we can do better and e.g. add some command that is going to check if your env is compatible for a smooth upgrade. Also, we might need to add support for Envoy params to hot restart envoy: https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/operations/hot_restart#:~:text=In%20addition%20to%20robust%20statistics,connections%20during%20the%20drain%20process. https://github.com/kumahq/kuma/issues/1920
