core: VdsSelector changes for CPU Thread Handling (2/4)

This patch series adds support for CPU Thread Handling in which host
CPU threads can be considered as cores on a per-cluster basis for the
purpose of VM startup/shutdown/migration.

Patch 2: update host selection algorithm to take advantage of cpu
threads.

VdsSelector now uses an "effective" core count.  This is a direct
plug-in replacement for using the physical CPU count, and is only in
effect when the host CPU has SMT enabled, and the cluster is set to
count CPU threads as cores.
