* 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"}]%
# use restful api to run a network instance
$> curl -H "Content-Type: application/json" -X POST 127.0.0.1:11211/api/v1/network/de3f5b8f-0f2f-d9d0-fb30-a2ac8951d92f -d '{"config": "listeners = [\"udp://0.0.0.0:12344\"]"}'
# use restful api to get network instance info

```
* move rpc-build out of easytier dir and make it a independant project
* easytier core use launcher
* fix flags not print on launch
* allow launcher not fetch node info
* abstract out peer rpc impl
* fix arm gui ci. see https://github.com/actions/runner-images/pull/10807
* add easytier-web crate
* fix manual_connector test case
1. remove some unessesary copy in cli parse code of string
2. make some member function into non-member function to avoid taking the self reference.
3. use if let Some(..) instead of if xxx.is_some() to avoid copy and unwrap
This patch removes Tarpc & Tonic GRPC and implements a customized rpc framework, which can be used by peer rpc and cli interface.
web config server can also use this rpc framework.
moreover, rewrite the public server logic, use ospf route to implement public server based networking. this make public server mesh possible.
the punching task creator doesn't check if the task is already
running, and may create many punching task to same peer node.
this patch also improve hole punching by checking hole punch packet
even if punch rpc is failed.
* correctly set mtu, and allow set mtu manually
* communicate between enc and non-enc should not panic
* allow loading cfg from file
* allow change file log level dynamically
