Postfix LDAP configs are now generated at startup to `/etc/postfix/ldap/<KIND>.cf`
(`users`, `groups`, `aliases`, `domains`, `senders`) from these sources, later ones take precedence:
1. Defaults (`version = 3`, `result_attribute = mail`, `senders`: `mail, uid`).
2. `LDAP_<SETTING>` ENV for all configs.
3. The custom config `ldap-<KIND>.cf` from the DMS config volume (now also supported for `senders`).
4. `POSTFIX_<KIND>_<SETTING>` ENV for a single config.
A config without `query_filter` is not generated and its lookup table is not configured
(including `smtpd_sender_login_maps` with `SPOOF_PROTECTION=1`). Previously all lookup
tables were always configured, as the default configs shipped by the image always existed.
Breaking:
- `LDAP_QUERY_FILTER_{USER,GROUP,ALIAS,DOMAIN,SENDERS}` are renamed to
`POSTFIX_{USERS,GROUPS,ALIASES,DOMAINS,SENDERS}_QUERY_FILTER` (an error is logged when the old ENV is set).
- `/etc/postfix/ldap-*.cf` moved to `/etc/postfix/ldap/*.cf`, the default configs (with default query filters) were removed.
Reworked from the original "Config Templates" proposal: Dovecot (already reworked for Dovecot 2.4)
and SASLAuthd are unchanged, and no template files or additional dependencies (`zenv`, `envsubst`) are required.
