Add config-read and run thread_birds with arguments.

Please rebase your branch onto the latest main.
There will be conflicts because, for example, we don't use push/pop boilerplate anymore and instead do this:

class config_t
{
public:
	config_t() = default;

	SERIALIZABLE(nat64stateful_id, dscp_mark_type, dscp, ipv6_prefixes, ipv4_prefixes, announces, next_module);

public:
	nat64stateful_id_t nat64stateful_id;
	common::eDscpMarkType dscp_mark_type{common::eDscpMarkType::never};
	uint8_t dscp{};
	std::vector<common::ipv6_prefix_t> ipv6_prefixes;
	std::vector<common::ipv4_prefix_t> ipv4_prefixes;
	std::set<common::ip_prefix_t> announces;
	controlplane::state_timeout state_timeout;
	std::string next_module;
	common::globalBase::flow_t flow;
};

That's just an example of the existing code. Note how we use the SERIALIZABLE macro with the names of the fields used for serialization

Updated bird-import-proto and this branches.

Suggested change

	inline static const std::string socketStr = "socket";
	inline static const std::string vrfStr = "vrf";
	static constexpr auto socketStr = "socket";
	static constexpr auto vrfStr = "vrf";

[ol-imorozko]

Since everything is public, why not just

Suggested change

	class bird_import_t
	{
	public:
	SERIALIZABLE(socket, vrf);
	public:
	inline static const std::string socketStr = "socket";
	inline static const std::string vrfStr = "vrf";
	std::string socket;
	std::string vrf;
	};
	struct bird_import_t
	{
	std::string socket;
	std::string vrf;
	static constexpr auto socketStr = "socket";
	static constexpr auto vrfStr = "vrf";
	SERIALIZABLE(socket, vrf);
	};

[ol-imorozko]

I guess we need

Suggested change

	void config_parser_t::loadConfig_route_bird(controlplane::base_t& baseNext,
	void config_parser_t::loadConfig_route_bird([[maybe_unused]] controlplane::base_t& baseNext,

[ol-imorozko]

interchange those lines, and now we will be able to benefit from moving import object, which is essentially two std::string's

Suggested change

	birdsImport.push_back(import);
	YANET_LOG_INFO("loadConfig_route_bird: socket(%s), vrf(%s)\n",
	import.socket.data(),
	import.vrf.data());
	}
	YANET_LOG_INFO("loadConfig_route_bird: socket(%s), vrf(%s)\n",
	import.socket.data(),
	import.vrf.data());
	birdsImport.push_back(std::move(import));
	}

Is every module is also a rib module? I don't quite understand.
Also, dynamic_cast will inevitably lead to some errors, if, for example, we decide to change class hierarchy.
Can we use other things here? Like maybe we can utilize one or two virtual functions?

Suggested change

	(void)vrf;
	YANET_GCC_BUG_UNUSED(vrf);
