As a (rudimental) way of directing and affecting the
placement logic implemented by the scheduler, support
vCPU hard affinity.
Basically, a vCPU will now be assigned only to a pCPU
that is part of its own hard affinity. If such pCPU(s)
is (are) busy, the vCPU will wait, like it happens
when there are no free pCPUs.
