[SPARK-18742][CORE]readd spark.broadcast.factory conf to implement
er-defined BroadcastFactory
## What changes were proposed in this pull request?
After SPARK-12588 Remove HTTPBroadcast [1], the one and only
implementation of BroadcastFactory is TorrentBroadcastFactory. No code
in Spark 2 uses BroadcastFactory (but TorrentBroadcastFactory) however
the scaladoc says [2]:
/**
* An interface for all the broadcast implementations in Spark (to allow
* multiple broadcast implementations). SparkContext uses a user-specified
* BroadcastFactory implementation to instantiate a particular broadcast
for the
* entire Spark job.
*/
which is not correct since there is no way to plug in a custom
user-specified BroadcastFactory.
It is better to readd spark.broadcast.factory for user-defined
BroadcastFactory
