Metadata provides certain information about a Filehandle, and you can specify which pieces
of information you will receive back by passing in optional parameters.

```python
from filestack import Client

client =  Client('API_KEY')
filelink = client.upload(filepath='/path/to/file/foo.jpg')
metadata = filelink.get_metadata()
# or define specific metadata to receive
metadata = filelink.get_metadata({'filename': true})
```
