This PR aims to optimize current operator synchronization procedure. Currently, we use goroutine to poll and call
changeCluster
API. However, it is prone to lead to unexpected race condition.As illustrated in the above figure, the former
changeCluster
may override the latter. This PR instead utilizes CR status and requeuing reconciliation. Besides, this PR also optimize project structure, moving core functionality to "pkg" folder and bumping go version to 1.21 (keep aligned with Dockerfile).
