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 #4345

Pull request overview

Syncs eng/common/testproxy certificate artifacts and tooling with azure-sdk-tools PR 15515 by introducing an OpenSSL-based certificate rotation flow (CA + leaf cert) for the test proxy’s HTTPS setup.

Changes:

  • Added rotate.sh to regenerate a self-signed CA, a localhost leaf cert, and a bundled PFX for Kestrel/test-proxy usage.
  • Updated certificate/config files to use a CA (dotnet-devcert.crt) and a non-CA localhost leaf (localhost.crt / localhost.conf).
  • Added a local .gitignore to prevent generated key/CSR/serial artifacts from being committed.

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