refactor camunda client in apih
Switched CamundaClient to use restTemplate Combined clients into one CamundaClient Initial setup of exception handling in camundaclient Initial fix of compilation issues Switched CamundaClient constructor Updated how url is set in CamundaClient Updated auth to fix tag mismatch warning Added throwing ClientConnectionException to client Updated ServiceInstancesTest cases Updated error handling for CamundaClient Updated how response is returned Fixed failing unit tests in apih infra Refactored response handler for responseentity Fixed failing unit tests in apih Removed old unit tests for client Import cleanup for unneeded changes Updated to use new CamundaClient Updated CamundaClient and ResponseHandler tests Removed unused RequestHandler Issue-ID: SO-2834 Signed-off-by: Benjamin, Max (mb388a) <mb388a@att.com> Change-Id: I82ff489c9c939a7e8ec0e48476daf7e45baa5f20
