Lin Ma 40f70d4fe5 virt-install: add param cache.mode and cache.level for option '--cpu'
libvirt supports guest CPU cache by commit df13c0b, So add this feature
to virt-install to configure cpu L3 cache mode.

Currently, The valid values are 'passthrough', 'emulate' or 'disable'.
say:
  --cpu host-passthrough,cache.mode=passthrough
or
  --cpu $CPU,cache.mode=emulate,cache.level=3
or
  --cpu $CPU,cache.mode=disable
