sanity-meta-openstack.bbclass: add class for bbappend files checking

Add a new class sanity-meta-openstack.bbclass,
to check whether necessary settings are available
for bbappend files and preferred version setting
in this layer to be effective and warn users if not.

In addition, a variable SKIP_SANITY_META_OPENSTACK_CHECK
is added to enable users to explicitly skip the
checking to avoid unwanted warnings.
