Rust's default HTTP stack - reqwest - does not support a self-signed TLS certificate.
Instead, we split the CA out while retaining the old dotnet-devcert.crt public key PEM.
dotnet-devcert.pfx is still the key pair for the server TLS certificate, but is signed by the separate CA.

This should require no code changes to other languages' test-proxy implementations.

Investigating some potential issues in .NET that may exist elsewhere but don't want to keep these open forever.
