sparkles: custom user bind and ephemeral mounts (#692)

Browse Source 
* ✨ custom user bind and ephemeral mounts

Users can now specify custom and ephemeral mounts in cloud-init under
the `install` section, e.g.:

```
users:
 - name: kairos
...
install:
  auto: true
  device: "auto"
  bind_mounts:
  - /mnt/bind1
  - /mnt/bind2
  ephemeral_mounts:
  - /mnt/ephemeral
  - /mnt/ephemeral2
...
```
Ephemeral mounts are mounted as RW - but changes are discarded when the
machine is restart.
Bind mounts will persist changes after restarted.

This is a fix for #210
