This is a temporary fix (until I think of something better) for https://nexedi.erp5.net/bug_module/20150609-1736CE7
Uses Ansibles shell module to execute chown.

In a new playbook that only installs the new erp5-show, this new script also does better
checking. Makes sure that the services are actually running (instead of just seeing if the table is populated)

after reverting bad commits, change service to shell (service only supports real system services like sshd)

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

This reverts commit 2e708284.

This reverts commit 2b1eb630.

This reverts commit b2ce2ed6.

This reverts commit 5ebb6c16.

This reverts commit df7cb56c.

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

This reverts commit f119007e.

This reverts commit e2852caa.

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
