This change introduces a basic role to copy the contents of /etc/ceph
between the controller and subnodes during orchestrate-devstack allowing
a multinode ceph job to be introduced by
I9ffdff44a3ad42ebdf26ab72e24dfe3b12b1ef8b.
Note that this role is only used when devstack-plugin-ceph is enabled.

For compute migration to work, the stack user needs to be configured
with passwordless ssh between all hosts involved in the migration.
Reuse the build ssh-key for this, which is already distributed for
user root.

Document that orchestrate-devstack requires a linear strategy in the
invoking play. Also enforce the strategy in devstack.yaml.

Extend the devstack job so that it can support both single and multinode
cases. Multinode mode require extra settings in devstack configuration,
some of which as subnode specific, some controller specific.
Also keep a simple devstack-multinode job defined for now so we can run
a multinode job in devstack gate, until the full tempest multinode job
is ready to match the old
gate-tempest-dsvm-neutron-multinode-full-ubuntu-xenial-nv.
Fixing multinode also requires sharing the CA configuration between
controller and peers, overlay network configuration for communication
between virtual machines and running discover_hosts for nova after the
subnode has been setup.
The extra orchestration required for multinode is encoded in a
dedicated role to allow for jobs in other repos to re-use it.
