Description

Please provide a description of your changes:

• What problem are you solving?
  • Enable iterating over query results so that we don't have to load them in memory. Intent is to store the results in an array structure backed by the likes of pandas and numpy
  • The existing execute_query_one_by_one would also work, but it is not as convenient as an iterator.
• Any expected impact on downstream packages/services?
  • No, just an extension of the feature set
• Reference issue # if available.
  • DTL-1622

Checklist

• I added a test to verify the new functionality.
• I verified this PR does not break soda-extensions.
