### What changes were proposed in this pull request?

This PR proposes to use an existing active Spark session instead of `SparkSession.getOrCreate` in pandas API on Spark.

### Why are the changes needed?

Because it shows warnings for configurations not taking effect as below:

Otherwise, it attempts to create a new session, and shows warnings as below:

```python
>>> ps.range(10)
21/12/14 16:12:58 WARN SparkSession: Using an existing SparkSession; the static sql configurations will not take effect.
21/12/14 16:12:58 WARN SparkSession: Using an existing SparkSession; some spark core configurations may not take effect.
21/12/14 16:12:58 WARN SparkSession: Using an existing SparkSession; the static sql configurations will not take effect.
