    Apply scheduler limits to Exact* filters

    The DiskFilter, RamFilter and CoreFilter scheduler filters set the
    resource limit on the HostState object during filtering. This is
    later checked in compute during the claim, and used to enforce
    the allocation ratios in a safe manner. The Exact* filters do not
    set the resource limits, so scheduler race conditions can result
    in multiple bare metal instances claiming a single host.

    This change sets the resource limits on the HostState object in
    the ExactCoreFilter, ExactDiskFilter and ExactRamFilter, ensuring
    that only a single baremetal instance can claim a compute host.
