How topolvm components work

1. operator watch the TopolvmCluster(CRD)
2. operator watch the operator-setting ConfigMap
3. operator start discover devices Daemonset
4. operator start ConfigMap controller to watch lvmd ConfigMap if TopolvmCluster created
5. TopolvmCluster controller create preparevg Job,Topolvm-controller Deployment depend on TopolvmCluster
6. preparevg Job on specific node check disk that provided in TopolvmCluster and create volume group, if volume group created successfully and then create lvmd ConfigMap for the node
7. ConfigMap controller finds the new lvmd ConfigMap then create Topolvm-node Deployment
8. TopolvmCluster controller update TopolvmCluster status
