feat: Add connection pool connection check parameters

[shaohuzhang1]

The provided code looks mostly correct and does not contain any major issues. However, I would suggest a few minor optimizations and changes:

1. Consistency in Key Capitalization: Ensure that all dictionary keys use consistent capitalization (or lowercase), such as pool_size, max_overflow, etc.

2. Comments: Consider adding comments to explain each key-value pair for clarity. This is just a suggestion and doesn't affect the functionality of the function.

Here's the modified version with these suggestions:

                 "MAX_OVERFLOW": int(self.get('DB_MAX_OVERFLOW')),
