The idea with this role is to install the root key from the on-disk
RSA secret. However, when this play runs against localhost it doesn't
match the host-variable defined root_rsa_key.
This is being run nested -- the executor Ansible task has forked the
Ansible we have installed on the bridge which is now installing this.
"connection: local" does what we want here -- it makes ansible assume
bridge.openstack.org is 127.0.0.1 -- which it is -- and avoids us
having to worry about the bootstrap ssh-ing back to itself.
This is a fixup for Iebaeed5028050d890ab541818f405978afd60124
