Pass hadoop confs specifed via Spark confs to URLStreamHandlerfactory

Why are the changes needed?

BEFORE

➜  spark git:(SPARK-31692) ✗ ./bin/spark-shell --conf spark.hadoop.fs.file.impl=org.apache.hadoop.fs.RawLocalFileSystem

scala> spark.sharedState
res0: org.apache.spark.sql.internal.SharedState = org.apache.spark.sql.internal.SharedState@5793cd84

scala> new java.net.URL("file:///tmp/1.txt").openConnection.getInputStream
res1: java.io.InputStream = org.apache.hadoop.fs.ChecksumFileSystem$FSDataBoundedInputStream@22846025

scala> import org.apache.hadoop.fs._
import org.apache.hadoop.fs._

scala>  FileSystem.get(new Path("file:///tmp/1.txt").toUri, spark.sparkContext.hadoopConfiguration)
res2: org.apache.hadoop.fs.FileSystem = org.apache.hadoop.fs.LocalFileSystem@5a930c03

AFTER

➜  spark git:(SPARK-31692) ✗ ./bin/spark-shell --conf spark.hadoop.fs.file.impl=org.apache.hadoop.fs.RawLocalFileSystem

scala> spark.sharedState
res0: org.apache.spark.sql.internal.SharedState = org.apache.spark.sql.internal.SharedState@5c24a636

scala> new java.net.URL("file:///tmp/1.txt").openConnection.getInputStream
res1: java.io.InputStream = org.apache.hadoop.fs.FSDataInputStream@2ba8f528

scala> import org.apache.hadoop.fs._
import org.apache.hadoop.fs._

scala>  FileSystem.get(new Path("file:///tmp/1.txt").toUri, spark.sparkContext.hadoopConfiguration)
res2: org.apache.hadoop.fs.FileSystem = LocalFS

scala>  FileSystem.get(new Path("file:///tmp/1.txt").toUri, spark.sparkContext.hadoopConfiguration).getClass
res3: Class[_ <: org.apache.hadoop.fs.FileSystem] = class org.apache.hadoop.fs.RawLocalFileSystem

The type of FileSystem object created(you can check the last statement in the above snippets) in the above two cases are different, which should not have been the case

Does this PR introduce any user-facing change?

No

How was this patch tested?

Thank you for updating, but the following is insufficient.

new URL("s3://<s3_path>/").openConnection().getInputStream

For example, people can try like the following in Apache Spark 3.0.0 RC1. Could you elaborate a little more in a reproducible way which the other people can follow?

scala> spark.version
res3: String = 3.0.0

scala> new java.net.URL("s3://1.txt").openConnection().getInputStream()
java.net.MalformedURLException: unknown protocol: s3

I have come up with an repro with Local filesystem, which will be easier for testing
