control-plane: packet-ccm with cloud-provider-equinix-metal

This commit removes the Packet Cloud Controller Manager a.k.a
packet-ccm as part of the migration to Equinix Metal.

In its place, `cloud-provider-equinix-metal` is installed.

For new Lokomotive clusters there won't be any difference because well
the are fresh clusters.

However, for existing clusters, users would need to uninstall the
`packet-ccm` helm release and then proceed with cluster upgrade using
`lokoctl cluster apply ...`.

Note: During upgrade the user must pass the flag
`--skip-pre-update-health-check`.

Execution steps for existing clusters:

1. Uninstall `packet-ccm` helm release

```
helm uninstall packet-ccm --namespace kube-system

```

2. Upgrade Lokomotive cluster to the latest release

Note: Do not forget the `--skip-pre-update-health-check` flag

```
lokoctl cluster apply --skip-components --skip-pre-update-health-check
```
