Support of 'document' type

tRESTclient is able to return 'document' attribute. When it is replaced by a tck/tHTTPClient, we have to add a tMap to transform the XML string to a 'document' with this routine call:

ParserUtils.parseTo_Document(incomingRow.body)

It could be great if, when a tck connector send a record with String attribute and if this attribute is mapped to an attribute of the rwoStruct that have the 'document' type to directly call the 'parseTo_Document' routine.

(maybe need to be discussed first since it will be a the first time the studio TCK integration will depends on a routine.)

( Currently, when a tck connector receive a studio record with and attribute of document type, it generates a java exception with root cause:
Caused by: java.lang.IllegalArgumentException: Unexpected class: routines.system.Document
We was able to remove the document input attribute (it was not use finally).
For the output, the tHTTPClient returns the XML payload as a String. We had to introduce a tMap to transform the String to a document using :
ParserUtils.parseTo_Document(incomingRow.body)
And it was ok after.)

Solution 1: serialize/deserialize from/to record the document as an object, and parse the document in in rowstruct/record visitors of component-runtime-di. With the talend type id_document.

Support case 2:
if we've a string value and rowstruct destination field is a document , we need to create a document and assign it to the rowstruct field.

Support case 3:
handle document type in dynamic
