Add KrknAI Orchestrator Implementation

[YiqinZhang]

Introduces a new orchestrator implementation for krkn AI chaos testing that follows the same lifecycle pattern as the existing E2E orchestrator.

Changes

New Files

• pkg/krknai/krknai.go: Implements KrknAIOrchestrator that satisfies the orchestrator.Orchestrator interface
• cmd/osde2e/krknai/cmd.go: Adds new CLI command osde2e krknai with similar flags to the test command

Modified Files

• cmd/osde2e/main.go: Registers the new krknai command in the CLI

Implementation Details

The KrknAIOrchestrator implements all required orchestrator methods:

• Provision(): Identical to E2E - loads cluster context, provisions/reuses cluster, installs addons
• Execute(): Simplified placeholder that returns success without running tests
• AnalyzeLogs(): Identical to E2E - performs AI-powered log analysis on failures
• Report(): Identical to E2E - collects and writes cluster logs
• PostProcessCluster(): Identical to E2E - runs must-gather, updates cluster properties, extends expiration
• Cleanup(): Identical to E2E - deletes cluster if configured
• Result(): Returns the orchestrator result with exit code and status

CLI Usage

The new command can be invoked as:

osde2e krknai [flags]
