Scheduler section of doc needs some changes

[koolhead17]

SimpleScheduler is no more supported with Grizzly at least i don`t see it in the github code.

Also http://docs.openstack.org/folsom/openstack-compute/admin/content/ch_scheduling.html

Since we have a Cinder as a separate project

scheduler_driver=nova.scheduler.multi.MultiScheduler
volume_scheduler_driver=nova.scheduler.chance.ChanceScheduler
compute_scheduler_driver=nova.scheduler.filter_scheduler.FilterScheduler
scheduler_available_filters=nova.scheduler.filters.standard_filters
scheduler_default_filters=AvailabilityZoneFilter,RamFilter,ComputeFilter
least_cost_functions=nova.scheduler.least_cost.compute_fill_first_cost_fn
compute_fill_first_cost_fn_weight=-1.0

This needs some modification. On a default devstack install the only option which comes to nova.conf now is

compute_scheduler_driver = nova.scheduler.filter_scheduler.FilterScheduler

We also need to replace existing multi scheduler definition with new one

https://review.openstack.org/#/c/9022/

This offers a default scheduler driver that will be used by the
multischeduler for requests that are not destined for the
compute or volume topic. This is useful for OpenStack extensions
that want to use the nova-scheduler to schedule requests to
compute nodes but provide their own manager and topic.
