[LIVY-863] Missing JVM class imports for Spark3

## What changes were proposed in this pull request?

Description of the problem: https://issues.apache.org/jira/browse/LIVY-863

The proposed fix consists of adding the missing imports that upstream Spark has when it's initiating the Java Gateway.
See the imports of Spark here: https://github.com/apache/spark/blob/87bf6b0ea4ca0618c8604895d05037edce8b7cb0/python/pyspark/java_gateway.py#L153

As far as I am aware, the java_import() does not fail or fails silently if the imported class does not exist.
But I might need to add some code to account for different Spark versions, looking for some guidance on this.

## How was this patch tested?

Tested with both valid and "bogus" imports by reviewers.
