Add flags to consul connect envoy for metrics merging. (#9768) 

Allows setting -prometheus-backend-port to configure the cluster
envoy_prometheus_bind_addr points to.

Allows setting -prometheus-scrape-path to configure which path
envoy_prometheus_bind_addr exposes metrics on.

-prometheus-backend-port is used by the consul-k8s metrics merging feature, to
configure envoy_prometheus_bind_addr to point to the merged metrics
endpoint that combines Envoy and service metrics so that one set of
annotations on a Pod can scrape metrics from the service and it's Envoy
sidecar.

-prometheus-scrape-path is used to allow configurability of the path
where prometheus metrics are exposed on envoy_prometheus_bind_addr.

@ -82,6 +82,19 @@ proxy configuration needed.
In cases where either assumption is violated this flag will prevent the
command attempting to resolve config from the local agent.
- `-prometheus-backend-port` - Sets the backend port for the "prometheus_backend"
cluster that `envoy_prometheus_bind_addr` will point to. Without this flag,
`envoy_prometheus_bind_addr` would point to the "self_admin" cluster where Envoy metrics
are exposed. The metrics merging feature in consul-k8s uses this to point to the
merged metrics endpoint combining Envoy and service metrics.
Only applicable when `envoy_prometheus_bind_addr` is set in proxy config.
- `-prometheus-scrape-path` - Sets the path where Envoy will expose metrics on the
`envoy_prometheus_bind_addr` listener. Default is `/metrics`. For example, if `envoy_prometheus_bind_addr`
is `0.0.0.0:20200`, and this flag is set to `/scrape-metrics`, prometheus metrics would
be scrapable at `0.0.0.0:20200/scrape-metrics`.
Only applicable when `envoy_prometheus_bind_addr` is set in proxy config.
- `-- [pass-through options]` - Any options given after a double dash are passed
directly through to the `envoy` invocation. See [Envoy's
documentation](https://www.envoyproxy.io/docs) for more details. The command
