[SQL] WriterContainer refactoring - WIP
## What changes were proposed in this pull request?
This is a work-in-progress pull request that I'm putting it out here for
just early preview before I create a JIRA ticket. The refactoring removes the
class hierarchy in WriterContainer, and turns everything into just functions.
The previous code setup made it pretty difficult to track the actual
dependencies on variables and setups because the driver side and the executor
side were using the same set of variables.
## How was this patch tested?
N/A - this should be covered by existing tests.
