Title: Add ESP support for Json formatted response

Refactors ESP message serialization code, encapsulates format
specific code, and adds support for JSON responses.

For now, desired format is specified in the request url by adding
an extension to the method name at the end of the path.

i.e. for XML:
http://host:8010/MyService/MyMethod.xml?Wuid=W20120621-123710

for JSON:
http://host:8010/MyService/MyMethod.json?Wuid=W20120621-123710

Fixes gh-2741.
