Adding heat to this bug since doing a stack update on a stack containing
a port and a server will fail if the server is replaced.

Title:
  Pre-created ports get deleted on VM delete

Status in Orchestration API (Heat):
  New
Status in OpenStack Compute (Nova):
  In Progress

Bug description:
  1) Pre create a port using port-create
  2) Boot a VM with nova boot --nic port_id=<created port>
  3) Delete a VM.

  Expected: VM should boot using provided port_id at boot time.
  When VM is deleted, port corresponding to pre-created port_id should not get deleted,
  as a lot of application, security settings could have port properties configured in them in a large network.

  Observed behavior:
  There is no way, I could prevent port_id associated with VM from being deleted with nova delete.
