Wait for compute service to check in
With cell v2, on initial bring up, discover hosts can't run unless all
the compute nodes have checked in. The documentation says that you
should run ``nova service-list --binary nova-compute`` and see all
your hosts before running discover hosts. This isn't really viable in
a multinode devstack because of how things are brought up in parts.
We can however know that stack.sh will not complete before the compute
node is up by waiting for the compute node to check in before
completing. This happens quite late in the stack.sh run, so shouldn't
add any extra time in most runs.
Cells v1 and Xenserver don't use real hostnames in the service table
(they encode complex data that is hostname like to provide more
topology information than just hostnames). They are exempted from this
check.
