This pr is the correction of bug 85.

The 202 response of the POST methods in the following resources:
- /vnf_instances/{vnfInstanceId}/scale
- /vnf_instances/{vnfInstanceId}/scale_to_level
- /vnf_instances/{vnfInstanceId}/change_flavour
- /vnf_instances/{vnfInstanceId}/terminate
- /vnf_instances/{vnfInstanceId}/heal
- /vnf_instances/{vnfInstanceId}/operate
- /vnf_instances/{vnfInstanceId}/change_ext_conn

contained a VNF instance object in their body what
is not needed.

Also the alarmId parameter added to the POST of /alarms/{alarmId}/escalate
