Move collectd

Collectd can be used for more than just OpenStack. To make things more
generic, we are moving to collectd-openstack for OSP collectd. As well
as collectd-generic for things that are not OpenStack specific.

+ (akrzos) nit picking some whitespace and simplifing the generic collectd config.
