GO Standard Lib Patch

For now, GO-GCSPROXY needs to use a patched go, net/http is updated to handle TE:identity.

Follow the instruction below to build a patched go command and toolchain:

1. git clone git@github.com:golang/go.git
2. git checkout go1.23.0 go-gcsproxy uses 1.23
3. Make changes to [your-go-repo-root]/src/net/http/transfer.go. Search "eshen" in here as refernce.
4. Run make.bash under [your-go-repo-root]/src/. It generates go command under bin/ and toolchain under pkg/
5. Add [your-go-repo-root]/bin/ into PATH env, so the patched go command and toolchain will be used when you launch go-gcsproxy.
6. Go to go-gcsproxy directory and launch the proxy(make uses the patched go).
