  5. gravel: nodes/mgr: make ceph.conf managed by cephadm 

    So we can have a consistent and up to date ceph.conf across all nodes,
let's rely on cephadm to manage it.

We don't drop the ceph.conf initially shared with a joining node because
we want to ensure that node is able to perform operations on the cluster
as soon as join finishes, and we don't want to have to wait for cephadm
to write the ceph.conf.

  13. images: config.sh: install etcd from custom location 

    We needed to patch aetcd3 and the fix hasn't been merged upstream yet.
So, we created our own package and uploaded it somewhere it can be
reached. This is what we are installing now.
