refactor: Share a common helper (vhost builder) for sourcing domains (#2620)
* chore: Split vhost helper method and use filepath vars - Helpers `accounts.sh` and `aliases.sh` can move their vhost code into this helper. - They share duplicate code with `bin/open-dkim` which will also leverage this vhost helper going forward. * chore: Sync vhost generation logic into helper - Chunky commit, but mostly copy/paste of logic into a common method. - `bin/open-dkim` additionally wrapped relevant logic in a function call and revised inline docs. * chore: Include LDAP vhost support - Revises notes for LDAP vhost support. - This now ensures LDAP users get vhost rebuilt to match the startup script for when change detection support is enabled. - `bin/open-dkim` will additionally be able to support the default `DOMAINNAME` var (set via `helpers/dns.sh`) for LDAP users instead of requiring them to provide one explicitly. * chore(`bin/open-dkim`): Ensure `DOMAINNAME` is properly set - This will ensure LDAP users insert the same `DOMAINNAME` value as used during container startup. - The container itself should panic at startup (during `helpers/dns.sh`) if this isn't configured correctly already, thus it should not introduce any breaking change to users of this utility? * chore: Set the 2nd value as blank `_` Line is split by a delimiter such as white-space (or via IFS: `|`), the blank `_` var is to indicate we're not interested in that value, but still leverage how `read -r` works, instead of splitting the var ourselves first thing. * chore: Remove shellcheck disable lines No longer applicable with the switch to `_`
