Consolidate LoadTesting tools

[g2vinay]

Consolidates Get/List and Create/Update tools.

[Copilot]

Pull request overview

This PR consolidates Load Testing tools by merging similar commands to reduce redundancy and simplify the API surface. Specifically, it combines testrun get + testrun list into a single testrun get command, and testrun create + testrun update into a single testrun createorupdate command. The consolidation maintains all existing functionality while making the command structure more intuitive.

Changes:

• Merged testrun get and testrun list into a single get command that accepts either --testrun (for single run) or --test (for listing all runs)
• Merged testrun create and testrun update into a single createorupdate command
• Updated service registrations, serialization contexts, and test files to reflect the consolidation
• Added comprehensive test guide documenting the consolidated commands

• The documentation still lists the old separate commands (testrun create, testrun list, testrun update) that are being removed in this PR. These should be updated to reflect the consolidated commands: "testrun get" (which now handles both get and list) and "testrun createorupdate" (which now handles both create and update).
