Reduce flickering caused by the spinner a bit

Normally  dialog  checks  to  see if it is running in an xterm, and in that case
tries to suppress the initialization strings that would make it  switch  to  the
alternate screen.  Switching between the normal and alternate screens is visual-
ly distracting in a script which runs dialog several times.

install-chef-suse: Check for package installed

SUSE-Manager doesn't support patterns. The pattern requirements moved to
a package for now and the pattern just requires the single package.
Adjust the check so it's fine when the patterns-cloud-admin package is
installed.

Restructured stoney release folder
JSON reformatting
Replaced dell_bios with bios and dell_raid with raid
Added ```#!/usr/bin/env bash``` to dev script

In order to execute the dev script on other operating systems the env
decision for the bash binary should be fine.

In a specific case i tried
to execute the dev script on a Mac dev machine. As the system bash is
quite outdated i installed a newer bash version that is not localted at
```/usr/bin``` and i was not able to execute the bash script. Even
```/usr/local/bin/bash dev``` won't work as the "parameters" are getting
parsed wrong.
Replaced development release with stoney entries
Removed unused releases from stoney
Migrated changes from stoney to development

Releases restructuring
Stop excessive chef-server log

The logs grow to ~200MB in a couple of hours when we deploy, because it
logs the full params (eg, full content of node objects) at the info
level. The log is not really useful as it is, so instead, only log at
the warn level.

Run zypper commands in non-interactive mode

Otherwise it might be stalling forever on input that
is never going to come.
