"--check --diff" doesn't template fresh koala configs

[Grzegorz Bialas]

kayobe overcloud service deploy --check --diff doesn't re-create content of etc/kolla.

What happened:

Scenario:
1. I have checkout with already templated etc/kolla
2. I am making changes in config in etc/kayobe
3. I am running kayobe overcloud service deploy --check --diff
4. I see that changes are not applied in output.
5. Files in etc/kolla have still old values.

**Environment**:

Kaoyobe: yoga release (bellow you will find exact tag)

$ cat /etc/redhat-release
Rocky Linux release 9.2 (Blue Onyx)

Package Version
-------------------------- ------------
ansible 5.10.0
ansible-core 2.12.10
kayobe 12.9.1.dev18

Ahh, this is because the kolla config generation is being skipped because we are in check mode. Maybe we can override that? A workaround is to first generate the kolla config with:

kayobe overcloud service deploy -kt none

and then run with --diff, --check.
