Yusuke Kuoka 6661406b75 Metrics provider for deployments and services behind Envoy ...

Assumes `envoy:smi` as the mesh provider name as I've successfully tested the progressive delivery for Envoy + Crossover with it.

This enhances Flagger to translate it to the metrics provider name of `envoy` for deployment targets, or `envoy:service` for service targets.

The `envoy` metrics provider is equivalent to `appmesh`, as both relies on the same set of standard metrics exposed by Envoy itself.

The `envoy:service` is almost the same as the `envoy` provider, but removing the condition on pod name, as we only need to filter on the backing service name = envoy_cluster_name. We don't consider other Envoy xDS implementations that uses anything that is different to original servicen ames as `envoy_cluster_name`, for now.
