Code Issues Proposed changes

roles: Remove use of NovaVcpuPinSet from ComputeRealTime 

This has been deprecated and replaced by 'NovaComputeCpuDedicatedSet'
and 'NovaComputeCpuSharedSet', as seen in change
Ibba4273526392985ede6da2ef3fec66a61407777. Update the ComputeRealTime
role to reflect this.
