BroadcastFactory — Pluggable Broadcast Variable Factories

BroadcastFactory is the interface for factories of broadcast variables in Spark.

Note	As of Spark 2.0, it is no longer possible to plug a custom BroadcastFactory in, and TorrentBroadcastFactory is the only implementation.

BroadcastFactory is exclusively used and instantiated inside of BroadcastManager.
