Fields support

[krismarc]

Fields support. No idea if it fits into your design. However, if you agree, I could come up with some tests, readme update etc.

Fields param as specified in the API description. Navigable object would contain only data from includes returned by fields query params.

fields = {"space.organization": ["guid", "name"], "space": ["guid,name,relationships.organization"] }
service_instances = client.v3.service_instances.list(fields=fields)

for service_instance in service_instances:
    space = service_instance.space()
    org = space.organization()
    print("Org name:" + org["name"])
    break

./test.py
