Upgrade ElasticUtils to version 0.10.1

Why does this have to go to settings? I'd add it here as

```python
class UserProfileMappingType(MappingType, Indexable):
    MAPPING_TYPE_NAME = 'foo'

    def get_mapping_type_name(cls):
        return UserProfileMappingType.MAPPING_TYPE_NAME
```

If you have a good reason for it to be in settings, then ES_MAPPING_TYPE_NAME is a bad name as it's too generic.
