Rename and deprecate public methods that contains 'master' in the name in 'server' directory

[tlfeng]

Description

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. Then alternative methods are created.

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

In directory - OpenSearch.server.main  (totally 28 method 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()

The backport to 2.x failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-2.x 2.x
# Navigate to the new working tree
cd .worktrees/backport-2.x
# Create a new branch
git switch --create backport/backport-3647-to-2.x
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick -x --mainline 1 1510b942bc05a89928e576300119f62871e5a1fd
# Push it to GitHub
git push --set-upstream origin backport/backport-3647-to-2.x
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-2.x

Then, create a pull request where the base branch is 2.x and the compare/head branch is backport/backport-3647-to-2.x.
