polarathene 692b433535 feat: `DEFAULT_RELAY_HOST` can now also use relay credentials ENV 
- Remove comment regarding `smtp_sasl_password_maps = static:${RELAY_USER}:${RELAY_PASSWORD}`, it could be used but `main.cf` presently has `644` permissions vs the `sasl_passwd` file permissions of `600`, less secure at preventing leaking of secrets (ignoring the ENV exposure itself).
- Move the `main.cf` settings specific to relayhost credentials support / security into to the relevant function scope instead. This also allows for the configuration to be applied by a change detection event without container restart requirement.
- Outer functions for setup and change detection to call have a clearer config dependency guard, as does the `_legacy_support()`.
- These changes now support `DEFAULT_RELAY_HOST` to leverage the relay credentials ENV as well.
- `DATABASE_RELAYHOSTS` is available in scope to the functions called here that reference it.
