Merge pull request #2 from michaeltchapman/heat

Heat
Disable selinux - issues on vagrant boxes
Ensure there are no offloads anywhere
Use new rabbitmq repo ensure parameter
Add debugging packages to base
Add offload removal to mirror
Handle rabbitmq module package strangeness
Remove build node from test run

Build nodes should be their own stage in the pipeline so remove
from the integration testing (which consumes a build node IP for
packages)
Add basic ssh configuration

Turn off GSSAPI auth because it makes test envs awkward for sharing
Increase test timeout
Use icehouse so it works with juno and havana keystones
Add environments for heat testing
