Mirror redirector
In order to fully utilize our numerous mirrors, we must create a HTTP mirror redirector for use in `apk`.
I have looked into using GeoDNS for this, but considering mirrors store alpine on different paths (i.e. /alpinelinux, /alpine-linux, /alpine) this is impossible.
I will test mirrorbits for this, and keep this issue updated with progress.
