Working setup with web server and database server on separate hosts
Added some placeholders for Phabricator configuration
Only grant MySQL access to Phabricator databases
Specify domain instead of hostname
Set `log.access.path` in Phabricator configuration.

The Phabricator access log can provide more detailed information about Phabricator access than normal HTTP access logs (for instance, it can show logged-in users, controllers, and other application data).
Set `metamta.default-address` and `metamta.domain` configuration options.
Set `metamta.single-reply-handler-prefix` configuration so that Phabricator doesn't take up an entire domain.
Enabled `metamta.precedence-bulk`.

If this option is enabled, Phabricator will add a "Precedence: bulk" header to transactional mail (e.g., Differential, Maniphest and Herald notifications).
Enable `celerity.minify` in a production environment.

This option minifies static resources by removing whitespace and comments.
