Mark Goddard 86eb21dd98 Don't assume etcd group exists in baremetal role
The baremetal role does not currently assume too much about the
inventory, and in kayobe the seed is deployed using a very minimal
inventory.

Icf3f01516185afb7b9f642407b06a0204c36ecbe added a reference to the etcd
group in the baremetal role, which causes kayobe seed deployment to fail
with the following error:

    AnsibleUndefinedVariable: 'dict object' has no attribute 'etcd'

This change defaults the group lookup to an empty list.
