Fixed#17
Add new API call to get all the autoscalers currently managed by

```
curl http://localhost:8000/autoscaler
```
Add command into the CLI to get this list
```
export ORBITER_HOST=http://localhost:8000 orbiter autoscler ls
```
Add command into the CLI to print all the events fired by the daemon:
```
export ORBITER_HOST=http://localhost:8000 orbiter system events
```
