SEA Session Configuration Fix: Explicitly convert values to str

[varun-edachali-dbx]

What type of PR is this?

• Bug Fix

Description

This disparity was observed on running test_ssp_passthrough with use_sea as True in #594.

Currently, without explicit conversion of the values of the session_configuration to str, the case of some of the values may not be as expected in the response. Particularly, in test_ssp_passthrough, we get the response as [ansi_mode, true] instead of [ansi_mode, True]. To align with the Thrift implementation (which also does this), we explicitly cast our values to str to ensure the same configuration structure is received by the Databricks deployment regardless of backend choice.

How is this tested?

• Unit tests
• E2E Tests
• Manually - test_spp_passthrough in Complete Fetch Phase (for INLINE disposition and JSON_ARRAY format) #594.
• N/A
