Cells assumes 1:1 compute-service:compute-node mapping

[Jim Rollenhagen]

Cells capacity calculation seems to assume one compute_node per nova-compute service. It calculates capacity data by service name, overwriting the value for each compute_node. This results in the cell only showing capacity for one compute_host for each nova-compute service in the cell.

Observed running Ironic, where there are many compute_hosts in a nova-compute service.

    Fix cells capacity calculation for n:1 virt drivers

    The capacity calculation in cells assumes a 1:1 mapping for
    compute_hosts:nova-compute. Fix this calculation to allow for
    drivers that have an n:1 mapping.
