Bug Description

fq-name confilict was happened while creating physical interface by WebUI. All physical interfaces were deleted before re-creating physical interface.

There was no xe-0/0/6 on WebUI and /physical-interfaces on Rest API, however xe-0/0/6 was available on Zookeeper. Hence, following error message was shown on WebUI.
""FQ Name: /fq-name-to-uuid/physical_interface:default-global-system-config:QFX1:xe-0/0/6 exists already with ID: 5d59589b-a76e-4bb1-b84b-86fe5f801f63""

Also Zookeeper had following data;
ls /fq-name-to-uuid/physical_interface:default-global-system-config:QFX1:xe-0/0/6
[]

xe-0/0/6 was created successfully after deleting above data from Zookeeper.

"parent-type" is not present in json data during post request. This causes an exception post allocation of uuid in zookeeper.
This leak of uuid(zookeeper nodE) causes 409 error on subsequent creation of physical interface with that name.

Clean up fq_name_to_id mapping if parent_type is missing in obj_dict

If the parent_type field is missing in the JSON body if POST request, an exception
is raised while access it. This exception occurs after the uuid is allocated in zookeeper
Since the exception is not cause, the dbe_release is not called to release the fq_name_to_id
binding

Fix return error from ifmap_<type>_alloc function if parent type is required and missing in the POST request
