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.

Relates to Azure/azure-sdk-for-rust#4345

Pull request overview

Syncs eng/common/testproxy certificate assets and tooling with the upstream azure-sdk-tools changes from Azure/azure-sdk-tools#15515, primarily around how the Test Proxy’s HTTPS dev certificate is configured/rotated.

Changes:

  • Added a rotate.sh helper to regenerate the localhost TLS cert chain and re-bundle into dotnet-devcert.pfx.
  • Updated TLS OpenSSL config (localhost.conf) to generate a proper non-CA leaf cert and adjusted related certificate assets.
  • Introduced supporting CA config (ca.conf) and a local .gitignore for generated key/CSR/serial artifacts.

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