Add flag to dump yaml definitions

[aledbf]

Running the conformance test suite we could find a particular test is not ok. The yaml definition helps to reproduce the problem without spending time trying to reproduce what is being executed underneath

[aledbf]

Example of the output:

=== RUN   TestSuite
Feature: Host rules
  An Ingress may define routing rules based on the request host.

  If the HTTP request host matches one of the hosts in the
  Ingress objects, the traffic is routed to its backend service.
