Description

1) Add yarn.node-labels.manager-class, by default it's will not store anything to file system
2) Use above at least in some places: RMNodeLabelsManager, RMAdminCLI. Convert DummyNodeLabelsManager into a MemoryNodeLabelsManager
3) Document that RM configs and client configs for yarn.node-labels.manager-class should match
4) fs-store.uri -> fs-store.root-dir
5) Similarly FS_NODE_LABELS_STORE_URI
6) For default value of fs-store.uri, put it in /tmp. But creaat /tmp/hadoop-yarn-${user}/node-labels
