Title:
  cloud-init clean does not remove /etc/network/interfaces.d/50-cloud-
  init.cfg

Status in cloud-init:
  Expired

Bug description:
  `cloud-init clean` does not remove
  `/etc/network/interfaces.d/50-cloud-init.cfg`

  How to reproduce:

  1. ubuntu 16.04.5

  2. install a static cloud-init config containing network v2
  e.g.

  ```
  network:
    version: 2
    ethernets:
      eth0:
        addresses:
          - "192.168.0.1"
  ```

  3. Install a *new* cloud-init config which disables network
  (this is because cloud-init network v2, among other bugs *ignores* the `metric` directive - but that is not this bug):

  ```
  network:
    config: disabled
  ```

  4. Run `cloud-init clean && cloud-init init`

  5. The file `/etc/network/interfaces.d/50-cloud-init.cfg` is still
  there

  6. Manually remove `/etc/network/interfaces.d/50-cloud-init.cfg` and
  run clean+init again ... it is not recreated.

  This means that /etc/network/interfaces.d/50-cloud-init.cfg created
  under cloud-init is *not* deleted when running `cloud-init clean` ==
  bug == unexpected behavior.
