add an attribute to manage default behavior of package installation

[Matt Ray]

In openstack-common add an attribute to specify whether we want the default action for OpenStack package installation to be :install or :upgrade, since there are folks in both camps. Set the default to :install, but it can easily be overridden in a single place.

node['openstack']['packages']['action'] = :install

A previous implementation of this allowed for service-specific overrides.

node['openstack']['identity']['packages']['action'] = node['openstack']['packages']['action']

so you could override only the ones you care about. This pattern should probably be carried forth in the attributes files for each service.

Closing this issue, as there is a blueprint for this feature currently under discussion.
