Order parameters are not lowerCased when passed to another MS

[thib3113]

When I call the Tasks microservice, with order : order[createdAt]=DESC, it seems DESC is directly passed to camunda, so camunda say :

400 Bad Request` response:
{"type":"InvalidRequestException","message":"Cannot set query parameter 'sortOrder' to value 'DESC'"}

The full error coming from tasks microservice :

Client error: `GET api.workflow.dev.ds/rest/task?tenantIdIn=f0d47297-fedf-4163-b19c-d3eb9a818503&sortBy=created&sortOrder=DESC&firstResult=0&maxResults=10` resulted in a `400 Bad Request` response:
{"type":"InvalidRequestException","message":"Cannot set query parameter 'sortOrder' to value 'DESC'"}

sending the order in lowerCase resolve the problem .
( after some research in Camunda, it seems API only allow asc or desc, no other cases )
