While going through the manual CLI flow with some people on the team, there was some confusion with the `coder daemon` command - the fact there was no output to confirm that the daemon started:
```
coder ~/coder (bryphe/fix/daemon-log) $ dist/coder_linux_amd64/coder daemon
```
This PR just adds a simple log to confirm that the daemon has started:
```
coder ~/coder (bryphe/fix/daemon-log) $ dist/coder_linux_amd64/coder daemon
2022-03-16 17:57:20.358 [INFO] <daemon.go:53> daemon started {"url": "http://127.0.0.1:3000"}
```
Just throwing this out there. Feel free to reject if you have concerns about adding this @kylecarbs !
