Issue

The tool ipa-migrate is able to migrate DNS records but does not migrate DNS forward zones.

Steps to Reproduce

1. install source ipa server and add a dns forward zone: dnf install -y freeipa-server-dns; ipa-server-install --domain ipa.test --realm IPA.TEST --setup-dns --auto-forwarders -a Secret123 -p Secret123 -U; echo Secret123 | kinit admin; ipa dnsforwardzone-add ad.test --forward-policy=only --forwarder=$IP
2. install destination ipa server: dnf install -y freeipa-server-dns; ipa-server-install --domain ipa.test --realm IPA.TEST --setup-dns --auto-forwarders -a Secret123 -p Secret123 -U; echo Secret123 | kinit admin
3. migrate data from source to destination: on destination ipa server: ipa-migrate --migrate-dns -n -D cn=directory\ manager -w Secret123 prod-mode source.ipa.test

Actual behavior

The DNS forward zone is not migrated from source to destination

# ipa dnsforwardzone-find
----------------------------
Number of entries returned 0
----------------------------

Expected behavior

The DNS forward zone should also be migrated

# ipa dnsforwardzone-find
  Zone name: ad.test.
  Active zone: True
  Zone forwarders: 10.11.12.13
  Forward policy: only
----------------------------
Number of entries returned 1
