Add chef attribute for ram_allocation_ratio config option

The default value is "1.0", which essentially disables host RAM overcommit (bnc#784345)
See http://docs.openstack.org/essex/openstack-compute/admin/content/scheduler-filters.html#ramfilter

Add two options to barclamp UI and handle them in chef too

We add support for the cpu_allocation_ratio/ram_allocation_ratio options for
nova-scheduler (ram_allocation_ratio was already a chef attribute, but with a
value not changeable in the barclamp).

Do not mark new options as required

This creates an issue for existing proposals, since the JSON data will
only have the new options if they get changed; most users trying to save
will face an error because of the schema.

Having them not required is okay since the cookbooks is using a sane
default for the values.

Remove nova user attribute for the proposals

There is no good reason to change the defaults from the default attributes.
