rgw: add 'inline_data' zone placement info option

Adds a new RGW zone placement info option to control whether
an object's first data chunk is placed in the head object.
This allows admins to make a tradeoff between optimizing for
PUT/GET performance vs. DELETE performance for some cluster
configurations.
