new event TabCompleteRequestEvent and deprecate TabCompleteEvent

Players with permission bungeecord.multiple_connect can have multiple connections with the same Minecraft account.
The UUID and player name is altered to avoid collision with other player:
UUID : xxxxxxxx-xxxx-VIxx-xxxx-xxxxxxxxxxxx
- The UUID version (V above) is now the provided version + 8 (for online player, it is 4, so it becomes C).
- The I digit will follow the index of the duplicated player : first duplicated player is 1, second one is 2.
- The name of the player will be the real player name, followed by the character "." (dot) followed by the duplication index.

Bedrock accounts connected using the Floodgate plugin will not be able to connect multiple times due to the risk of xUID collision.

+ * Event called when a downstream server (on 1.13+) sends the command structure
+ * to a player, but before BungeeCord adds the dummy command nodes of
+ * registered commands.
+ * <p>
+ * BungeeCord will not overwrite the modifications made by the listeners.
+ *
+ * <h2>Usage example</h2>
+ * Here is a usage example of this event, to declare a command structure.
+ * This illustrates the commands /server and /send of Bungee.
+ * <pre>
+ * event.getRoot().addChild( LiteralArgumentBuilder.&lt;CommandSender&gt;literal( "server" )
+ *         .requires( sender -&gt; sender.hasPermission( "bungeecord.command.server" ) )
+ *         .executes( a -&gt; 0 )
+ *         .then( RequiredArgumentBuilder.argument( "serverName", StringArgumentType.greedyString() )
+ *                 .suggests( SuggestionRegistry.ASK_SERVER )
+ *         )
+ *         .build()
+ * );
+ * event.getRoot().addChild( LiteralArgumentBuilder.&lt;CommandSender&gt;literal( "send" )
+ *         .requires( sender -&gt; sender.hasPermission( "bungeecord.command.send" ) )
+ *         .then( RequiredArgumentBuilder.argument( "playerName", StringArgumentType.word() )
+ *                 .suggests( SuggestionRegistry.ASK_SERVER )
+ *                 .then( RequiredArgumentBuilder.argument( "serverName", StringArgumentType.greedyString() )
+ *                         .suggests( SuggestionRegistry.ASK_SERVER )
+ *                 )
+ *         )
+ *         .build()
+ * );
+ * </pre>
+ *
+ * <h2>Flag a {@link CommandNode} as executable or not</h2>
+ * The implementation of a {@link com.mojang.brigadier.Command Command} used in
+ * {@link ArgumentBuilder#executes(com.mojang.brigadier.Command)} will never be
+ * executed. This will only tell to the client if the current node is
+ * executable or not.
+ * <ul>
+ *     <li>
+ *         {@code builder.executes(null)} (default) to mark the node as not
+ *         executable.
+ *     </li>
+ *     <li>
+ *         {@code builder.executes(a -> 0)}, or any non null argument, to mark
+ *         the node as executable (the child arguments are displayed as
+ *         optional).
+ *     </li>
+ * </ul>
+ *
+ * <h2>{@link CommandNode}’s suggestions management</h2>
+ * The implementation of a SuggestionProvider used in
+ * {@link RequiredArgumentBuilder#suggests(SuggestionProvider)} will never be
+ * executed. This will only tell to the client how to deal with the
+ * auto-completion of the argument.
+ * <ul>
+ *     <li>
+ *         {@code builder.suggests(null)} (default) to disable auto-completion
+ *         for this argument.
+ *     </li>
+ *     <li>
+ *         {@code builder.suggests(SuggestionRegistry.ALL_RECIPES)} to suggest
+ *         Minecraft’s recipes.
+ *     </li>
+ *     <li>
+ *         {@code builder.suggests(SuggestionRegistry.AVAILABLE_SOUNDS)} to
+ *         suggest Minecraft’s default sound identifiers.
+ *     </li>
+ *     <li>
+ *         {@code builder.suggests(SuggestionRegistry.SUMMONABLE_ENTITIES)} to
+ *         suggest Minecraft’s default summonable entities identifiers.
+ *     </li>
+ *     <li>
+ *         {@code builder.suggests(SuggestionRegistry.ASK_SERVER)}, or any
+ *         other non null argument, to make the Minecraft client ask
+ *         auto-completion to the server. Any specified implementation of
+ *         {@link SuggestionProvider} will never be executed.
+ *     </li>
+ * </ul>
+ *
+ * <h2>Argument types</h2>
+ * When building a new argument command node using
+ * {@link RequiredArgumentBuilder#argument(String, ArgumentType)}, you have to
+ * specify an {@link ArgumentType}. You can use all subclasses of
+ * {@link ArgumentType} provided with brigadier (for instance,
+ * {@link StringArgumentType} or {@link IntegerArgumentType}), or call any
+ * {@code ArgumentRegistry.minecraft*()} methods to use a {@code minecraft:*}
+ * argument type.
+ *
+ * <h2>Limitations with brigadier API</h2>
+ * This event is only used for the client to show command syntax, suggest
+ * sub-commands and color the arguments in the chat box. The command execution
+ * needs to be implemented using {@link PluginManager#registerCommand(Plugin,
+ * Command)} and the server-side tab-completion using {@link TabCompleteEvent}
+ * or {@link TabExecutor}.
