Queue is missing redis username support from url

Created by: StefanCenusa

Description

Queue doesn't parse the username out of the redis url. Of course, username could be passed with redis options, but I think it would be nice to parse/get all the information from the url string if possible.

function redisOptsFromUrl(urlString) {
  const redisOpts = {};
  try {
    const redisUrl = url.parse(urlString);
    redisOpts.port = redisUrl.port || 6379;
    redisOpts.host = redisUrl.hostname;
    redisOpts.db = redisUrl.pathname ? redisUrl.pathname.split('/')[1] : 0;
    if (redisUrl.auth) {
      redisOpts.password = redisUrl.auth.split(':')[1];
    }
  } catch (e) {
    throw new Error(e.message);
  }
  return redisOpts;
}

A simple solution would be:

if (redisUrl.auth) {
    const columnIndex = redisUrl.auth.indexOf(':');
    redisOpts.password = redisUrl.auth.slice(columnIndex + 1);
    if (columnIndex > 0) {
        redisOpts.user = redisUrl.auth.slice(0, columnIndex);
    }
}

Should I open a PR for this change?
