sol-compiler: build fails behind proxy since #1596

[thorstenhirsch]

Expected Behavior

build behind http proxy should work (as long as all internet connection use the http proxy)

Current Behavior

build fails with timeout when fetching list.json (solidity releases)

Possible Solution

With #1596 you changed from a static list of solidity releases to dynamically fetching it with this line:

src/utils/compiler.ts:        const versionList = await fetch('https://ethereum.github.io/solc-bin/bin/list.json');

However fetch is implemented in node-fetch, which does NOT respect http proxy configurations like environment variables or ~/.gitconfig. This seems to be done intentionally, the node-fetch guys write that node-fetch is on the wrong abstraction level, so if you're using it you have to implement the http proxy settings yourself (e.g. with an http-proxy-agent).

I suggest to switch from node-fetch to some other download library that respects environment variables http_proxy and https_proxy by default.

Steps to Reproduce (for bugs)

See ethereum-oasis-op/baseline#86.

Your Environment

Arch Linux (x64)
baseline (latest development version)
sol-compiler 4.0.2 (dependency of baseline)
