[#PETALSCDK-133] Change the format of fault content (SOAPFault --> Simple XML payload) - Petals Link JIRA

Description:

The CDK generates SOAPFault as fault. At JBI level, fault should be simple XML payload (see PETALSDISTRIB-133), transformed into SoapFault by the Petals BC Soap (~~PETALSBCSOAP-145~~).

Depends

This issue depends on:
~~PETALSCDK-130~~ Technical errors should NOT be transformed to Fault, and even less SOAPFault
~~PETALSCDK-134~~ Remove or refactor Exceptions around Fault

This issue blocks:
PETALSDISTRIB-133 Better management of errors versus faults in JBI exchanges
~~PETALSBCSOAP-145~~ JBI Errors should be transformed to SOAPFault
