no swap space for puppet deploys of overcloud-full

[Marios Andreou]

I am not sure yet if https://bugs.launchpad.net/tripleo/+bug/1464239 is related, but when deploying overcloud-full for puppet elements based deploy you don't get swap space. Even when you deploy with a flavor that has swap, it isn't enabled.

As discussed at https://bugzilla.redhat.com/show_bug.cgi?id=1245714 we should set the nova ram_allocation_ratio to reflect reality like '1.0'. This is done @ https://review.openstack.org/#/c/218944/

The swap space can be enabled right now by running swapon in a first boot script, like https://review.openstack.org/#/c/217796/ (and using a flavor that has swap defined).

    Set the nova scheduler ram_allocation_ration to 1.0

    We don't have swap space enabled on overcloud-full deploys
    as discussed at https://bugs.launchpad.net/tripleo/+bug/1491335

    The default is 1.5 so configure Virtual ram to physical ram
    allocation ratio to 1:1 so we don't allow overcommit.

https://review.openstack.org/#/c/289084/ shows how to enable swap and it landed, so I'm closing this fix released
