Text2sql execution accuracy metric updates

[oktie]

The goal is to add additional metrics and results to the output of the text2sql execution accuracy metric implementation. We used to produce just one number: 1 if the dataframe produced by the SQLs in pred and gold are the same, 0 otherwise. I've added scores to report 12 scores/outputs:

1. execution_result: if df responses match (same as before)
2. non_empty_execution_result: if dfs are non-empty and match
3. subset_non_empty_execution_result: if non-empty dfs and gt df subset of predicted df
4. non_empty_gold_df: if gt df is non-empty
5. gold_sql_runtime: ground truth query runtime
6. predicted_sql_runtime: predicted query runtime
7. pred_to_gold_runtime_ratio: ratio of predicted query runtime to gt query runtime
8. gold_error: if gt has an error
9. predicted_error: if predicted query has an error
10. ground truth dataframe
11. predicted query's dataframe
12. error message (if any)

What we used to get (output of examples/evaluate_text2sql.py):

num_of_instances (int):
    10

    0.12179476763080924

I also added non-execution accuracy metrics, that measure the validity and equivalence of the SQLs without running them. Example output from python examples/evaluate_text2sql.py:
