    Use inventory_hostname for Ceph bootstrap

    The inventory_hostname is more reliable than ansible_hostname for the
    way we use it here. If the deploy node cannot resolve the hostname of a
    target node (the operator is using IP addresses in their inventory), the
    bootstrap will fail with:

    "Host: x.x.x.x, Task: ceph : Fetching Ceph keyrings, Status:
    unreachable, Message: SSH Error: data could not be sent to the remote
    host. Make sure this host can be reached over ssh"
