Bug Description

The mistral workflow that derives deployment parameters for HCI (hyperconverged Compute and Ceph-OSD) currently assumes all CPU cores identified in the baremetal introspection data are available for sharing between Nova and Ceph.

When NovaVcpuPinSet (THT parameter) is defined, the HCI derived parameters workflow must base its calculations on the number of cores in the set, and not use the total number of cores identified in the introspection data. NovaVcpuPinSet limits the number of cores available to Nova, and that same limit applies to Ceph-OSD in an HCI deployment.

If this issue is not corrected, the HCI derived parameters workflow will generate incorrect values that may significantly impact the performance of an HCI node.

Use NovaVcpuPinSet when deriving HCI parameters

    When deriving deployment parameters for HCI (hyperconverged Nova compute and
    Ceph OSD nodes), use NovaVcpuPinSet to determine the number of CPU cores
    available for Nova and Ceph. When NovaVcpuPinSet isn't set, use all of the
    cores identified in the baremetal introspection data.

Reason: I need to purge the gate because TripleO CI gate has critical issues right now, I'll make this patch goes to the gate.
