This reverts commit 52bc3d33.

Okay these last commits are ugly... but service can't be used unless it is a real service (sshd for example). Changed to shell.

Fix for msg: this module requires key=value arguments (['slapos', 'node', 'format', '--now', '--alter_user=True'])

This module takes key value pairs, so we set the name to our service and arguments to the flags.

fixed bugs in wendelin-show to make it useable (looks for right xml key), also replace erp5 with wendelin

Use proper ERP5 cluster SR's URL and proper configuration.
