Adds support for setting node and volume name prefixes on a per-spec basis. This allows for different node specifications to use different names, e.g. 'controller' vs 'compute'. This change also fixes an issue where node names were not globally unique, only unique on a given hypervisor. This could cause issues if used with multiple hypervisors. This has been done by rewriting the scheduling logic, replacing the 'node index' concept with a more concrete reservation of IPMI ports (which are allocated per hypervisor), and decoupling this from generation of node names (which are allocated globally).
