[2.x] Rename and deprecate public methods that contains 'master' in the name in 'server' directory (#3647)

[tlfeng]

Description

Backport PR #3647 / commit 1510b94 into 2.x branch.

To support inclusive language, the master terminology is going to be replaced by cluster manager in the code base.
This PR deprecate public and protected methods that contains master terminology in the name in server directory, except those covered by issue #3542 and #3543.

List of public methods that contain master in name that will be deprecated in this PR:

In directory - OpenSearch.server.main  (totally 27 class definitions)
public boolean hasDiscoveredMaster() {
public boolean localNodeMaster() {
public void updateMappingOnMaster(Index index, Mapping mappingUpdate, ActionListener<Void> listener) {
public boolean isBecomeMasterTask() {
public Optional<DiscoveryNode> getMasterNode() {
public PutRequest masterTimeout(TimeValue masterTimeout) {
public RemoveRequest masterTimeout(TimeValue masterTimeout) {
public static boolean isMasterNode(Settings settings) {
public boolean isMasterNode() {
public boolean isLocalNodeElectedMaster() {
public ImmutableOpenMap<String, DiscoveryNode> getMasterNodes() {
public ImmutableOpenMap<String, DiscoveryNode> getMasterAndDataNodes() {
public Stream<DiscoveryNode> mastersFirstStream() {
public String getMasterNodeId() {
public DiscoveryNode getMasterNode() {
public boolean masterNodeChanged() {
public DiscoveryNode previousMasterNode() {
public DiscoveryNode newMasterNode() {
public Builder masterNodeId(String clusterManagerNodeId) {
public boolean isLocalNodeElectedMaster() {
protected void assertClusterOrMasterStateThread() {
public void addLocalNodeMasterListener(LocalNodeMasterListener listener) {
public MasterService getMasterService() { (not changed in this PR)
public static boolean assertClusterOrMasterStateThread() {
void connectToRemoteMasterNode(TransportAddress transportAddress, ActionListener<DiscoveryNode> listener); (in interface, and not changed in this PR)
TimeValue masterNodeTimeout() (in interface, and not changed in this PR)
public synchronized void updateFromMaster(
public ClusterState joinNodesAndBecomeMaster(ClusterState clusterState, List<DiscoveryNode> nodes) {

The below test classes will not be renamed, because they are used to test the deprecated master node behavior.

public void testDoesNothingByDefaultIfMasterNodesConfigured() {
public void testDoesNotBootstrapsOnNonMasterNode() {
public void testDoesNotBootstrapsIfLocalNodeNotInInitialMasterNodes() {
public void testFailBootstrapWithBothSingleNodeDiscoveryAndInitialMasterNodes() {
public void testFailBootstrapNonMasterEligibleNodeWithSingleNodeDiscovery() {
public void testIsMasterNode() {

Other changes:

• Changed 2 references of JoinTaskExecutor.newBecomeMasterTask() to use JoinTaskExecutor.newBecomeClusterManagerTask()
