Description

• Add cluster_domain column at SELECT_LIST in GetReplicationAnalysis()'s query.
• Set it to ClusterDetails.ClusterDomain.

In case this PR introduced Go code changes:

• contributed code is using same conventions as original code
• code is formatted via gofmt (please avoid goimports)
• code is built via ./build.sh
• code is tested via go test ./go/...

No test code for this, but I already deployed my company's test-environment and there is no problem.
