Enhancements on code quality and stability

[Syulin7]

Based on Arena 2024 roadmap, to enhance code quality and stability, I think we need to complete the following tasks.

• Run go fmt, go vet on the entire project. (chore: go fmt #1028)
• Run golangci-lint on the entire project. (chore: fix go lint. #1030)
• Add CI to run the tests for Go. (Add CI to run the tests for Go. #1031)
• Add CI to run Go unit test. (Add CI to run Go unit test. #1035)
• Upgrade Go version and dependencies (Upgrade Go version to v1.20 #1032, Support Kubernetes 1.26 and KServe 0.11.2 #1041)
• Enhancements on Arena SDK.
• Add CI to run integration test.
