[FEA] Log the shuffle manager class when shuffle manager is misconfigured

[gerashegalov]

Is your feature request related to a problem? Please describe.

Instead of just reporting "Cannot initialize ..."

spark-rapids/sql-plugin/src/main/scala/org/apache/spark/sql/rapids/GpuShuffleEnv.scala

Lines 106 to 113 in 47047a9

	def initShuffleManager(): Unit = {
	SparkEnv.get.shuffleManager match {
	case rapidsShuffleManager: RapidsShuffleManagerLike =>
	rapidsShuffleManager.initialize
	case _ =>
	throw new IllegalStateException(s"Cannot initialize the RAPIDS Shuffle Manager")
	}
	}

1. The code should log the "wrong" shuffle manager instance's class
2. For the case it is a classloader problem, also output the corresponding classloader of 1

I am planning to work on this.

For the context regarding the classloader. It is hard to reproduce but we have seen cases triggering

although the ShuffleManager class was correctly specified. In those cases rapidsShuffleManager is not instance of RapidsShuffleManagerLike. Thus. presumably classOf[RapidsShuffleManagerLike] is different than RapidsShuffleManagerLike reachable via org.apache.spark.SparkEnv.get.shuffleManager.getClass.getSuperclass.getInterfaces
