* Support running as a Windows service.
* Optimize startup logic contro
* When running in a Windows service environment, delegate the termination of the program to the win_service_event_loop function.
* Remove the use of std::ffi::OsString at the top.
* Support service manager
* Move the service-related features to be implemented in easytier-cli.
* Add a command line option work-dir to specify the working directory
Adjust the error handling logic
When the program is started by the Service Control Manager (SCM), it needs to call StartServiceCtrlDispatcher (which corresponds to service_dispatcher::start in the windows-service crate) to inform the SCM of the service's entry function. The SCM then calls the service entry function passed to StartServiceCtrlDispatcher. The process calling StartServiceCtrlDispatcher will block until the service's status is set to Stopped. If the current program is not run through the SCM, StartServiceCtrlDispatcher will return the error ERROR_FAILED_SERVICE_CONTROLLER_CONNECT, and the program will run according to its original mechanism. For more details about SCM, please refer to Microsoft's documentation.
This patch implement a restful server without any auth.
usage:
```bash
# run easytier-web, which acts as an gateway and registry for all easytier-core
$> easytier-web
# run easytier-core and connect to easytier-web with a token
$> easytier-core --config-server udp://127.0.0.1:22020/fdsafdsa
# use restful api to list session
$> curl -H "Content-Type: application/json" -X GET 127.0.0.1:11211/api/v1/sessions
[{"token":"fdsafdsa","client_url":"udp://127.0.0.1:48915","machine_id":"de3f5b8f-0f2f-d9d0-fb30-a2ac8951d92f"}]%

this patch optimize the udp hole punch logic:
1. allow start punch hole before stun test complete.
2. add lock to symmetric punch, avoid conflict between concurrent hole punching task.
3. support punching hole for predictable nat4-nat4.
4. make backoff of retry reasonable
introduce my peer route id and peer id is duplicated only when peer
route id is not same.
this problem occurs because update_self may increase my peer info
version and propagate to ther nodes.
