HTTP / HTTPS proxy option support

Hi,

I was trying to use the tool under a network where HTTP / HTTPS proxy is required for the Internet access, but it does not work.

Since there is no way to set the proxy on Node globally (e.g. HTTP_PROXY, HTTPS_PROXY), it would be great if the proxy option is offered by this tool.

Thank you.

We can use global-agent https://github.com/gajus/global-agent

1. Add the below to bin/cdxgen

if (process.env.GLOBAL_AGENT_HTTP_PROXY) {
  const globalAgent = require('global-agent');
  globalAgent.bootstrap();
}

1. Set an environment variable export GLOBAL_AGENT_HTTP_PROXY=http://127.0.0.1:8080
