Add Kuryr pods logs to gate results

When Kuryr is run in pods, logs of its services are not available in the
gate. This commit adds a post-run playbook that will copy information
about Kubernetes resources and logs of all pods into the results.

# This script takes bits from devstack-gate/functions/cleanup_host in a
# more generic approach, so we don't need to actually run devstack on the node
# to cleanup an host.
# Kubernetes resources
# TODO(dulek): It might be good to split that into Ansible tasks once it's
# stable. Until then script is easier to debug and test.
