Command

https://github.com/Microsoft/language-server-protocol/blob/master/protocol.md#command

Represents a reference to a command. Provides a title which will be used to
represent a command in the UI. Commands are identitifed using a string
identifier and the protocol currently doesn't specify a set of well known
commands. So executing a command requires some tool extension code.

interface Command {
    /**
     * Title of the command, like `save`.
     */
    title: string;
    /**
     * The identifier of the actual command handler.
     */
    command: string;
    /**
     * Arguments that the command handler should be
     * invoked with.
     */
    arguments?: any[];
}
