Bug Description

In Devstack:

When add 'scheduler_default_filters=RetryFilter,AvailabilityZoneFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter' to /etc/nova/nova.conf and restart nova-scheduler

When trying to run VMs nova-compute reports:

http://paste.openstack.org/show/20960/

In the past when RamFilter was disabled, unlimited Ram oversubscription was allowed.

I put this on the folsom-rc1 list to have it on the release radar since it's a regression in Folsom.

    Fix bugs in resource tracker and cleanup

    Fixes bugs in resource tracker:
    * Handle disk oversubscription
    * Handle suspended/powered off instances

    The usage model is changed to the old style that is
    based on actual instance usage on a compute host.
    (Not the current point in time of the hypervisor's
     reported host stats)

    There is now a 'limits' filter property that can be passed from
    the scheduler to the compute node to indicate that
    oversubscription of resources is desired:

    The 'limits' filter property is a dict with the following possible
    keys:

    * memory_mb - Specifies the memory ceiling for the compute node.
    * disk_gb - Specifies the disk space ceiling for the compute node.
    * vcpu - Specifies the max number of vcpus for the compute node.

    There is also some general cleanup and additional unit tests in
    an attempt to simplify down this function.
