[BE-26] Adapt NSXJsonInterceptor to allow overriding payload size limits and provide backwards compatible defaults. Introduced struts constants to configure manually:
nsx.struts.json.maxElements
nsx.struts.json.maxDepth
nsx.struts.json.maxLength
nsx.struts.json.maxStringLength
nsx.struts.json.maxKeyLength
[BE-26] Add NSXJSONWriter to allow custom object serialization. (Breaking: struts.json.writer is now configured as 'NSXJSONWriter'. When defined previously customizations should be moved to the NSXJSONWriter.)
