[yocto] [PATCH 1/2][Image Creator] Hob Cache for speed up switching

[Ke Liping]

From: Liping Ke <liping.ke at intel.com>

This patch is the centralized place for storing Hob attributes.
Most of informations in Prefs will be used when caching user-select
packages information. Those information will be the cache hash-key
which is useful in deciding whether the configuration combination
value has been cached or not
