Title: Allow custom server name with DOKKU_SERVER_NAME app env var

This allows to set a custom server name by setting the `DOKKU_SERVER_NAME` config var. It provides the functionality of 0cd1839ce857ffe83d369238968f48f2e6a99ded but outside the repo.
I used the same config name style as `DOKKU_CHECKS_WAIT` from the checks plugin.
