Log the suggested mirrors for download

### Feature Request

We often get reports of plugins that fail to download, and from running the install process in `--verbose` mode we can see where it has attempted to download a plugin from - this is often surprising as builds taking place in the US often appear to be redirected to EU/Japan.

Could we enhance the log output to show the recommended download location and all the extra "links", like a log representation of the `?mirrorlist` endpoint.
