Always enforce the crm-initial.conf

For some reason, the first time we do "crm configure load replace" just
after setting up the cluster, the settings get lost.

In the end, ensuring that the settings are set (on every chef run) is no
big deal. The only thing that we do is stop using "load replace", as
this would possibly remove stopped resources that we do not want to
lose. Instead, we just do "crm configure < crm-initial.conf", which is
good enough.
