[Implements #67302952] Rename `vcloud-configure-edge` executable

Rename the CLI command `vcloud-configure-edge` to `vcloud-edge-configure` to make the naming consistent with the other vCloud Tools using the format:

```
  vcloud-<entity>-<infinitive-verb>
```

Per the discussion in Pivotal: 67302952.

Leave the original executable in place with a deprecation warning and update the CHANGELOG accordingly.
