DefaultBootstrapAddresses are the hardcoded bootstrap addresses for IPFS. they are nodes run by the IPFS team. docs on these later. As with all p2p networks, bootstrap is an important security concern.

NOTE: This is here -- and not inside cmd/ipfs/init.go -- because of an import dependency issue. TODO: move this into a config/default/ package.
