Add support for telemetry endpoint

Contains some fixes included in https://github.com/microsoft/vscode/commit/b108bc8294ce920fcf2ee8d53f97c3bcf3316e1c

To test:
1. Look inside a build of code-server, inside `lib/vscode/vs/server/node/server.main.js`
2. Search for a `JSON.stringify` near `TelemetryClient`
3. throw in a `console.log()` before it and make sure it logs telemetry data
