Add *.main and *.ceph wildcard certificates for haproxy (#484)

The haproxy edge terminates TLS for hosts under `main.unkin.net` and `ceph.unkin.net`, which the single `*.unkin.net` wildcard does not cover.

- Add cert-manager Certificates for both wildcards from the `letsencrypt` ClusterIssuer.
- Reflect the minted secrets into the `haproxy` namespace.

Needs these records in the public unkin.net zone first:
`_acme-challenge.main.unkin.net. CNAME _acme-challenge.main.acme.unkin.net.`
`_acme-challenge.ceph.unkin.net. CNAME _acme-challenge.ceph.acme.unkin.net.`
