[SPARK-15416][PySpark]Display a better message for not finding classes
removed in Spark 2.0
## What changes were proposed in this pull request?
If finding `NoClassDefFoundError` or `ClassNotFoundException`, check if the
class name is removed in Spark 2.0. If so, the user must be using an
incompatible library and we can provide a better message.
## How was this patch tested?
1. Run `bin/pyspark --packages com.databricks:spark-avro_2.10:2.0.1`
2. type
`sqlContext.read.format("com.databricks.spark.avro").load("src/test/resources/episodes.avro")`.
It will show `pyspark.sql.utils.IncompatibilityException:
u'org.apache.spark.sql.sources.HadoopFsRelationProvider is removed in Spark
2.0. Please check if your library is compatible with Spark 2.0'`
