Add Helper or documentation about `host-resolver-rules` argument

[gnuletik]

The Chrome's host-resolver-rules can be quite handy when running local tests.

I think that it could be useful to either:

• add a note about this flag in the documentation
• add a helper to configure it in the launcher (but I'm not sure about the API)

Here is how I use it:

launch := launcher.New()

// Resolve all subdomains of `baseDomain` to localhost.
hostRules := []string{"MAP *." + baseDomain + " 127.0.0.1"}
launch.Set("host-resolver-rules", hostRules...)

What do you think?

Yes, BTW:

launch.Set("host-resolver-rules", hostRules...)

You can use this one as an example:
