Mark Goddard d1cd215c66 Validate instance_info.traits against node traits ...

The ironic node traits spec calls out that traits added to
instance_info.traits should be validated against the node's traits.  All
traits in instance_info.traits should exist in the node's traits.  This
protects us against race conditions between traits being removed from a
node in ironic, and the node's resource provider's traits being updated
in placement.

This change adds validation to do_node_deploy() and
validate_driver_interfaces() in the conductor manager, ensuring that all
instance traits are also node traits.
