WeichenXu 0e36ba6212 [SPARK-22644][ML][TEST] Make ML testsuite support StructuredStreaming test ... ## What changes were proposed in this pull request? We need to add some helper code to make testing ML transformers & models easier with streaming data. These tests might help us catch any remaining issues and we could encourage future PRs to use these tests to prevent new Models & Transformers from having issues. I add a `MLTest` trait which extends `StreamTest` trait, and override `createSparkSession`. So ML testsuite can only extend `MLTest`, to use both ML & Stream test util functions. I only modify one testcase in `LinearRegressionSuite`, for first pass review. Link to #19746 ## How was this patch tested? `MLTestSuite` added.
