- blackhole traffic that would cause the envoy to infinitely connect to itself
- add tests for the envoy config

Did you introduce this for a specific reason? This binary looks pretty serial...

No, I thought we would just add this per convention for new tests, since e.g.,
contrast/internal/fsstore/fsstore_test.go
Line 17 in 5a6afdd

I don't, was just curious.

Traffic to the TPROXY port (15006/15007) led to a traffic storm as envoy used the original destination to forward the traffic to, therefore forwarding it again to the TPROXY port where envoy listens. This commit introduces a Blackhole cluster where we send traffic to, that arrives on the TPROXY listeners and which original destination port is the TPROXY.
With increasing envoy config complexity it gets more difficult to parse the final envoy config. Therefore we introduce tests which compare the envoy config for specific scenarios with golden JSON representations of the expected output.
