Add special-case to node role state transition table for when the node
is not alive and we would otherwise transition to active.
Add after_create and before_destroy hooks to deployment that call the
appropriate role events for deployment roles.
Add on_deployment_create and on_deployment_delete role hooks.

These will be called whenever a role is bound or unbound from a deployment.
