CxService.setProjectRepositoryDetails has hard-coded error message

[james-bostock-cx]

The setProjectRepositoryDetails method (in the CxService class) has a hard-coded error message for when the request fails:

        try {
            log.info("Updating Source details for project Id {}", projectId);
            restTemplate.exchange(cxProperties.getUrl().concat(PROJECT_SOURCE), HttpMethod.POST, requestEntity, String.class, projectId);
        } catch (HttpStatusCodeException e) {
            log.error("Error occurred while updating Project source info for project {}.", projectId);
            throw new CheckmarxException("Error occurred while adding source details to project.  Please ensure GIT is defined within Checkmarx");
        }

This should be changed to report the error message from the response body. For example, given the following response:

{
    "messageCode": 12331,
    "messageDetails": "Failure occurred during GIT Browsing"
}

CxFlow should report the messageDetails (and, possibly, the messageCode) in the log.
