feat(api,ssh,gateway): remove refresh and use air

As refresh package, used to rebuild the service when the code changes,
seem don't be maintained anymore, we have decided to change to air, a
more modern alternative. Beyond that, we also added 'dlv' to the air,
allowing use to attach a debug to the service through the container's IP
on the port `:2345`.

With the container's IP in your hands, you just need to connect to it
using the 'dlv' connect command. It is worth to notice that, as
`agent`'s container runs on host network, you don't need to specify the
IP when debugging it.

```sh
dlv connect <IP>:2345
```

As the code built in the container lives in another GOPATH, you can
need to remap this path to your local environment. To perform that, you
can open or create the file `~/.config/dlv/config.yml`, and insert this
snippet.

```yml
substitute-path: [
  { from: "/go", to: "<GOPATH in your local machine>" }
]
```
