This change allows supporting the openresty package as installed on Ubuntu 18.04 from the official openresty package repository, while also returning general nginx support.
Closes#3675
While I do not agree with _every_ style change, this will force Dokku to have consistent formatting across all shell scripts, which is arguably a Good Thing™.
The command used to reprocess everything is:
```shell
shfmt -l -bn -ci -i 2 -w .
```
* fix rsyslog handling
* don't hardcode dokku path
* add documentation for ArchLinux package build
* add vagrant machine to run the ArchLinux specific steps
* add step in release process for ArchLinux
* enhance docs for easy ArchLinux steps
I have done the first steps to get dokku running for other distros like
openSUSE. I have simply replaced the important places within the core
plugins with a check for DOKKU_DISTRO that gets exported by dokku
itself. It just replaces the apt-get and service start/restart/reload
functionality with the openSUSE counterparts.
Two new hooks are implemented:
- pre-delete $APP
- post-delete $APP
The following are implemented in the `post-delete` hook:
- `$APP` directory deletion (00_dokku-standard)
- nginx reload (nginx-vhosts)
The following command can be executed by either the `dokku` or `git` user as `sudo`:
sudo /etc/init.d/nginx reload
