Bug Description

When VNF delete fails due to underlying system or software error, those VNFs transitions to PENDING_DELETE state. Now, vnf-delete on these PENDING_DELETE VNFs doesn't work and these VNFs are stuck for ever. We need to expose a API / CLI option for an admin to "force" the deletion of VNFs in PENDING_DELETE state.

$ tacker vnf-list -f csv
"id","name","description","mgmt_url","status","vim_id","placement_attr","error_reason"
"8d580075-e257-452b-9a15-acb8991a2fd1","my-vnf2","Demo example","{""VDU1"": ""192.168.120.5""}","PENDING_DELETE","ae91e663-27fa-4512-9b53-06c489ffd584","{u'vim_name': u'VIM0'}",""
"8ee1fa0f-b986-4a99-9b15-fafc32010ec6","my-vnf1","Demo example","{""VDU1"": ""192.168.120.11""}","PENDING_DELETE","ae91e663-27fa-4512-9b53-06c489ffd584","{u'vim_name': u'VIM0'}",""

$ tacker vnf-delete my-vnf1
VNF 8ee1fa0f-b986-4a99-9b15-fafc32010ec6 could not be found

This is still a problem in stable/newton. Any ideas how to to work around it? Deleting the tacker service and redeploying seems a pretty heavy solution.

I tried with Tacker 0.9.0 and the issue is till there. Adding some details.

I had an error (network name) in the VNFD and the deployment got stuck, then I tried to delete and it's pending forever.

vnf-list shows the VNF with status PENDING_DELETE
But, vnf-delete results in error - VNF couldn't be found.
