enable path to be sourced from the body similar to the id.

[dgcaron]

in order to add multiple messages to the same document in a json tree, we need a way to set the path dynamically. this PR enables to source the path from the contents of the message.

if the configured path is a json pointer, the value is searched for in the document and removed from the message. if the value isn't a json pointer, the value is treated as a static path inside a document (current behaviour).

example of dynamic path usage

config - couchbase.subdocument.path: /path
message 1 - { "id":"documentid", "path":"myproperty.value1", "foo":"bar"}
message 2 - { "id":"documentid", "path":"myproperty.value2", "foo":"baz"}

this would result in

{
  "myproperty": 
   {
       "value1":
        {
           "foo":"bar"
        },
        "value2":
        {
           "foo":"baz"
        }
   }
}

whereas a static path

config - couchbase.subdocument.path: myproperty.value1
message 1 - { "id":"documentid",  "foo":"bar"}
message 2 - { "id":"documentid",  "foo":"baz"}

would result in

{
  "myproperty": 
   {
       "value1":
        {
           "foo":"baz"
        }
   }
}

Hi @dgcaron, thanks for the PR. Just wanted to make sure you'd seen the comments in Gerrit. The only thing preventing merge is how the ByteBuf's backing array is accessed in SubDocumentWriter -- the other comments are just suggestions. Thanks, David
