Network communication auto encryption, or upgrade golang to 1.20, or compile wireguard by golang 1.18

[AlexNebula]

It seems that Occlum does not provide network communication auto encryption feature, I have one based on wireguard, but wireguard uses new features of golang 1.20. So, either Occlum provides network communication auto encryption feature (just like its file I/O auto encryption feature), or Occlum supports golang 1.20 so that I can integrate my network communication auto encryption module into Occlum, or there is a solution to compile wireguard by Occlum golang 1.18

Recently Occlum supported golang 1.20.
You can clone the ago1.20.12_for_occlum repo into your own docker development container and then compile and install it. You can refer to the steps in build.sh.
