Code Issues Proposed changes

update scheduler to use image-traits

Browse Source 
Update the scheduler to take into account the traits specified
as part of the image properties. The required traits from the
image are added to the resource request along with the traits
and resources from the flavor.

This change does not handle rebuilding of the instance, this
will come as part of a follow on patch.

Added unit and functional tests
