Fix ORC managed log collection

[winiciusallan]

When a failure in the CI occurs, the collectlogs script is not properly collecting logs for two reasons:

1. It is not using the FQDN name for the resources, which causes the script to collect the Kubernetes service resource, instead of the Openstack service managed by ORC
2. After the completion of kuttl test, it deletes all of the resources, preventing the script which runs afterwards to collect the managed resources.

This PR add the KUTTL_SKIP_DELETE flag to prevent kuttl of deleting the resources and use FQDN resource names.

Closes #855
