Description:
Several helpful examples are provided in the examples directory of this project. When running the examples/front-envoy example I am observing warnings in the log to do with Configuration does not parse cleanly as v3..

It would be very helpful for this example to use the most up-to-date config so that new users (such as myself) can create a usable deployment without warnings.

Repro steps:
In project:

1. cd examples/front-proxy
2. docker-compose up --build

Observe the below warning in the log output

Logs:

front-envoy_1  | [2020-10-09 15:01:12.982][7][warning][misc] [source/common/protobuf/utility.cc:294] Configuration does not parse cleanly as v3. v2 configuration is deprecated and will
 be removed from Envoy at the start of Q1 2021: envoy.config.filter.network.http_connection_manager.v2.HttpConnectionManager

The expectation is that this warning should not be emitted.
