ipahost: Remove dangling dns records during test setup

When testing ipahost through the test playbooks, if there are previous
DNS A/AAAA records, the test fails due to a false positive idempotence
issue.

This patch ensures that all DNS records for the test hosts are absent
before test execution.

This issue could be seen in the 2023-11-06 Azure Nightly pipeline
execution.
