Improve/silence WebpackDevServer client

[gaearon]

This doesn’t help anyone, it’s just annoying:

Similarly, these logs are not useful to us:

We should a PR to webpack-dev-server to deduplicate logs, and to optionally disable some of them. If it isn’t accepted, we should replace these parts with custom scripts—they are really small, easy to tweak, and almost never change.

I thought I'd just go ahead and file an issue first to gauge the interest. webpack/webpack-dev-server#540

Hi, could you guys check if this PR webpack/webpack-dev-server#579 works for you? I'm maintaining webpack-dev-server and interested to work with you to fix annoyances :).

Left a comment, thank you for looking at this!

Something that worked for me was changing this line in config/webpack.config.dev.js:
require.resolve('webpack-dev-server/client') + '?/',
to
require.resolve('webpack-dev-server/client') + '?http://0.0.0.0:0/',

After that, the requests actually all went through and it seems to be working correctly.

EDIT: currently using version 0.4.0

If you see this normally please file an issue describing your setup.
I see these errors when I stop the server (which is expected).

My issue is about the noisy reconnect behavior.
If you actually can't connect, that's a different problem, needing a separate issue.

For future reference, this has been fixed in dev-server v2 (in beta). See the changelog for more info.

Also backported to 1.x and now used by CRA (thanks!)
With exponential backoff I only see a few of these so I think it's fine now.
