Users currently have to provide the full class name for external data sources, like:
`sqlContext.read.format("com.databricks.spark.avro").load(path)`
This allows external data source packages to register themselves using a Service Loader so that they can add custom alias like:
`sqlContext.read.format("avro").load(path)`
This makes it so that using external data source packages uses the same format as the internal data sources like parquet, json, etc.
