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
