    Return vcpu pin set as set rather than list

    The current implementation of the libvirt driver makes mixed assumptions
    about the vcpu pin set returned from hardware.get_vcpu_pin_set(). Most
    places in the code assume its a set and perform set operations on the
    structure. However a few places assume it's a list. Given the mixed
    assumptions about the structure type, the existing code was trying
    to perform set operations on a list.

    This patch changes the get_vcpu_pin_set() method to return a set
    rather than a list and handles any edge cases where consumers need
    a list. It also updates any relevant unit tests accordingly.
