Major Description
In the bigtop_toolchain module, the puppet modules use hardcoded apache mirror sites to download component tar balls(for example, use ftp://mirror.reverse.net/pub/apache/maven/maven-3/3.0.5/binaries/apache-maven-3.0.5-bin.tar.gz to download maven).
In some cases the hardcoded mirror maybe very slow, causing the installation to be very slow or even fail.
We can use the "www.apache.org/dyn/closer.cgi" to choose apache mirrors automatically and faster the installatin.
