Title: [WIP][1.0][loader] cleanup filesystem loader, simplify logic, add factory.

This PR removes some config params: `formats` and `data_root`. Adds a factory so now we can configure several filesystem loaders.

```yaml
liip_imagine:
loaders:
default:
filesystem: ~
foo:
filesystem:
data_root: %kernel.root_dir%/../web
```

The logic is working, still have to add some tests.
