Basic adjustment for SUSE (package-names and init scripts)

Conflicts:
	chef/cookbooks/glance/recipes/common.rb
Use prefixed system user on SUSE
set secure permissions (bnc#771101)

Conflicts:
	chef/cookbooks/glance/recipes/api.rb
Fixed uid+gid for glance-manage version_control and db_sync.

We are using openstack-glance instead of glance.

I found this accidentally while stracing the disappearance of
/var/run/chef/client.pid (bnc#773182). Not sure of the impact but
the fixed version should be better[TM].

Conflicts:
	chef/cookbooks/glance/recipes/common.rb
disallow access to configs with PWs (bnc#774966)

Conflicts:
	chef/cookbooks/glance/recipes/registry.rb
	chef/cookbooks/glance/recipes/scrubber.rb
Remove code that finds ip addresses that we actually don't need

The scrubber configuration doesn't care about keystone. And the registry
recipe is not using IP addresses.
