Bucket#get (JsonObject) is allocating twice the memory for the document

Motivation

----------

When retrieving a document Bucket#get the netty buffer content is

duplicated before the parsing by Jackson.

Modifications

-------------

Wrap the ByteBuf in an inputstream. Jackson now directly parse the netty

ByteBuf content

Result

------

Reduced memory allocations

YMMV but in our test it was a ~10% reduction
