[SPARK-15052][SQL] Use builder pattern to create SparkSession
## What changes were proposed in this pull request?
This patch creates a builder pattern for creating SparkSession. The new
code is unused and mostly deadcode. I'm putting it up here for feedback.
There are a few TODOs that can be done as follow-up pull requests:
- [ ] Update tests to use this
- [ ] Update examples to use this
- [ ] Disable the old constructor so the only way to start a SparkSession
is through this builder pattern
## How was this patch tested?
Part of the future pull request is to clean this up and switch existing
tests to use this.
You can merge this pull request into a Git repository by running:
