Tiny Go webserver that prints os information and HTTP request to output

## Usage

### Paths

- `/data?size=n`: creates a response with a size `n`.
- `/echo`: webSocket echo.
- `/bench`: always return the same response (`1`).
- `/`: returns the whoami information (request and network information).
- `/api`: returns the whoami information as JSON.
- `/health`: heath check
    - `GET`, `HEAD`, ...: returns a response with the status code defined by the `POST`
    - `POST`: changes the status code of the `GET` (`HEAD`, ...) response.

### Flags

- `cert`: give me a certificate.
- `key`: give me a key.
- `port`: give me a port number. (default: 80)
