Do not copy bytes for cached serializations
...
Since cachingObject has the encoded data cached and they are not
supposed to change. It's memory efficient to just copy the slice
references.

update the watch server to use EncoderWithAllocator during object serialization.
...
It allows us to allocate a single buffer for the entire watch session and release it when a watch connection is closed.
Previously memory was allocated for every object serialization putting a lot of pressure on GC and consuming more memory than needed.

Make RequestScope be a pointer consistently for better memory use

RequestScope is a large struct and causes stack growth when we pass
it by value into multiple stack levels. Avoid the allocations for
this read only struct by passing a pointer.

Support Table and PartialObjectMetadata on watch
...
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{}`
