Add useProxies to registryMirror allowing to mirror more anything

[momiji]

Description

Add a new field in registryMirror, allowing to use proxies list to decide whether to use dragonfly.
By doing this, it is now possible to cache more than only blobs/sha256 urls, allowing to use dragonfly2 for other usage thatn docker registries, like yum repositories.

Also fix the whiteList test which is tested on direct request, although host is empty and canno tbe tested.

Please update the documentation in Chinese, I just can't do it.

I apologize as I've never done this before, but I guess once used to the PR process, it will be easier and less a pain for me :)

I've tested the fix and confirm is it working perfectly on my real environments, using the docker image built for this purpose on my github account.

Will there be a v2.0.2 or v2.1.0 version including the fix soon? Not sure if including the alpha changes is necessary.

Next release is v2.0.2. This change will be included.
