This allows us to not obtain a certificate and encrypt it with KMS when running the proxy locally during development.
Also updated FOSS build dagger version.

When not running locally, the logging formatter is set to convert the log record to a single-line JSON string that Stackdriver logging agent running in GKE will pick up and parse correctly.
Also removed redundant logging handler in the proxy frontend connection. They have two problems: 1) it is possible to leak PII when all frontend traffic is logged, such as client IPs. Even though this is less of a concern because the GCP TCP proxy load balancer masquerade source IPs. 2) We are only logging the HTTP request/response that the frontend connection is sending to/receiving from the backend connection, but the backend already has its own logging handler to log the same message that it gets from/sends to the GAE app, so the logging in the frontend connection does not really give extra information.
Logging of some potential PII information such as the source IP of a proxied connection are also removed.
Thirdly, added a k8s autoscaling object that scales the containers based on CPU load. The default target load is 80%. This, in connection with GKE cluster VM autoscaling, means that when traffic is low, we'll only have one VM running one container of the proxy.
Fixes a bug where the MetricsComponent generates a separate ProxyConfig that does not call parse method on the command line args passed, resulting default Environment always being used in constructing the metric reporter.
Lastly a little bit of cleaning of the MOE config script, no newlines are necessary as the BUILD are formatted after string substitution.

The quota handler terminates connections when quota is exceeded.
The next CL will add instrumentation for quota related metrics.

Dagger updated to 2.13, along with all its dependencies.
Also allows us to have multiple config files for different environment (prod, sandbox, alpha, local, etc) and specify which one to use on the command line with a --env flag. Therefore the same binary can be used in all environments.
