tool: Refactor base type Commands

Each command will be implemented as a CLI subcommand
command handers registration process:

    CLI::App app;
    auto base = app.add_subcommand("base");
    auto GetPLDMVersion = base->add_subcommand("GetPLDMVersion");
    /* register callback for GetPLDMVersion Command */
    GetPLDMVersion->callback(exec());
    CLI11_PARSER();

Each command will be implemented as a class. To avoid duplicate,
An interface class is abstracted as the base class for commands.

CommandInterface
{
	CommandInterface(CLI::App* app){
		app->callback([&](){exec();}) //register exec() to CLI11
	}
	virtual createRequestMsg();
	virtual parseResponseMsg();
	exec(){
		createRequestMsg();
		send_recv();
		parseResponseMsg();
	}
};

GetPLDMVersion : public CommandInterface
{
	GetPLDMVersion(CLI::App *app){
		app->add_option();  // add options for this command
	}
	...
}

Then, the main is like below:

int main()
{
	CLI::App app{"PLDM requester tool for OpenBMC"};
	auto base = app.add_subcommand("base");
	auto version = base->add_subcommand("GetPLDMVersion");
	GetPLDMVersion getPLDMVersion(version);
	CLI11_PARSE(app, argc, argv);
}
