Clean up the code paths that lead to objects being transformed and output with negotiation.
Remove some duplicate code that was not consistent. Now, watch will respond correctly to
Table and PartialObjectMetadata requests. Add unit and integration tests.
When transforming responses to Tables, only the first watch event for a given type will
include the columns. Columns will not change unless the watch is restarted.
Add a volume attachment printer and tighten up table validation error cases.
Disable protobuf from table conversion because Tables don't have protobuf because they
use `interface{}`
