Adds HW_CPU_HYPERTHREADING standard trait
This patch adds a new standard trait: HW_CPU_HYPERTHREADING. The resource provider decorated with this trait indicates that the hyperthreading is enabled on the provider. Partially Implements: blueprint cpu-resources Change-Id: I762a7f11bd10f93855850d09751415d35e5b38e1
