[FLINK-2809] [scala-api] Added UnitTypeInfo and UnitSerializer.
Created UnitTypeInfo and UnitSerializer, which will be created for a
DataSet[Unit].
Also added a test.
There is a funny situation in CollectionInputFormat.checkCollection: when
ExecutionEnvironment.fromCollection calls it, the call to type.getTypeClass()
returns void.class, even though it should be classOf[Unit]. This is probably
some automatic conversion that happens when classOf[Unit] passes from the Scala
world to the Java world. I worked around this by adding a check for this
specific case.
