The ConnectsTo relationship in a node can have an interface that
contains the Configure relationship. This interface would have
a lifecycle operation associated with it, something like a
configuration script requiring some input parameters.
In the Heat template, each of these lifecycle operation would
be implemented as a software config node.
This patch adds the handler in the main translation loop to
process the ConnectsTo relationship.
