Pull Request Overview

This PR fixes XEvent test failures by preventing orphaned event sessions through two key improvements: adding automatic session expiration via MAX_DURATION on SQL Server 2017+ and incorporating test names into session names for better traceability.

Key Changes:

Added version detection to conditionally set MAX_DURATION for XEvent sessions on SQL Server 2017+
Refactored XEventScope to accept test names as session prefixes for improved identification
Introduced ServerProperty enum for type-safe server property queries

[nitpick] The original comment referencing a specific Merlinbot PR (line 6 in the old version) has been replaced with a generic documentation link. While the new link is useful, removing the historical reference to the PR that suggested this configuration may reduce traceability. Consider keeping both the original PR reference and the new documentation link.
