Improve logging in tempest cleanup

* add additional handler so that INFO messages are printed to stdout
  besided tempest.log
* replace print commands by LOG.info calls
* when --debug argument used print DEBUG messages to stdout
* add additional debug messages to improve transparency of the cleanup
  execution
* use --debug argument within tempest-cleanup ansible role to see more
  details directly in the output
