The time has come.
These filters haven't been necessary since Ocata [1]
when the filter scheduler started using placement
to filter on VCPU, DISK_GB and MEMORY_MB. The
only reason to use them with any in-tree scheduler
drivers is if using the CachingScheduler which doesn't
use placement, but the CachingScheduler itself has
been deprecated since Pike [2]. Furthermore, as of
change [3] in Stein, the ironic driver no longer
reports vcpu/ram/disk inventory for ironic nodes
which will make these filters filter out ironic nodes
thinking they don't have any inventory. Also, as
noted in [4], the DiskFilter does not account for
volume-backed instances and may incorrectly filter
out a host based on disk inventory when it would
otherwise be OK if the instance is not using local
disk.
The related aggregate filters are left intact for
now, see blueprint placement-aggregate-allocation-ratios.

The admin config resize doc was linking to a now non-existent
user guide doc which was deleted in pike. This change imports
the resize user guide from the openstack-manuals stable/ocata
branch, fixes the link, and updates the resize user doc to
(1) link to our internal shutdown_timeout config option reference
and (2) link to the image properties doc in glance for the
os_shutdown_timeout image property.

non-FS based Storage Repository will be supported after vdi streaming
patches finished. Remove SR limitation in the document.
Change-Id: Idaf461c849ac28b46e8971e5dd2f0e986a9a5c32
With the new image handler, it creates an image proxy which
will use the vdi streaming function from os-xenapi to
remotely export VHD from XenServer(image upload) or import
VHD to Xenerver(image download).
The existing GlanceStore uses custom functionality to directly
manipulate files on-disk, so it has the restriction that SR's
type must be file system based: e.g. ext or nfs. The new
image handler invokes APIs formally supported by XenServer
to export/import VDI remotely, it can support other SR
types also e.g. lvm, iscsi, etc.
Note:
vdi streaming would be supported by XenServer 6.5 or above.
The function of image handler depends on os-xenapi 0.3.3 or
above, so bump os-xenapi's version to 0.3.3 and also declare
depends on the patch which bump version in openstack/requirements.

There is concern over the ability for compute nodes to reasonably
determine which events should count against its consecutive build
failures. Since the compute may erronenously disable itself in
response to mundane or otherwise intentional user-triggered events,
this patch adds a scheduler weigher that considers the build failure
counter and can negatively weigh hosts with recent failures. This
avoids taking computes fully out of rotation, rather treating them as
less likely to be picked for a subsequent scheduling
operation.
This introduces a new conf option to control this weight. The default
is set high to maintain the existing behavior of picking nodes that
are not experiencing high failure rates, and resetting the counter as
soon as a single successful build occurs. This is minimal visible
change from the existing behavior with default configuration.
The rationale behind the default value for this weigher comes from the
values likely to be generated by its peer weighers. The RAM and Disk
weighers will increase the score by number of available megabytes of
memory (range in thousands) and disk (range in millions). The default
value of 1000000 for the build failure weigher will cause competing
nodes with similar amounts of available disk and a small (less than ten)
number of failures to become less desirable than those without, even
with many terabytes of available disk.

This patch is the first step in syncing the nova host aggregate
information with the placement service. The scheduler report client gets
a couple new public methods -- aggregate_add_host() and
aggregate_remove_host(). Both of these methods do **NOT** impact the
provider tree cache that the scheduler reportclient keeps when
instantiated inside the compute resource tracker.
Instead, these two new reportclient methods look up a resource provider
by *name* (not UUID) since that is what is supplied by the
os-aggregates Compute API when adding or removing a "host" to/from a
nova host aggregate.

This adds a request filter that, if enabled, allows us to use placement
to select hosts in the desired availability zone by looking up the uuid
of the associated host aggregate and using that in our query for
allocation candidates. The deployer needs the same sort of mirrored
aggregate setup as the tenant filter, and documentation is added here to
make that clear.

There were several things wrong with this doc since the migration
in-tree in pike, which are handled here:
- Updated options to use the current names.
- Any mention of the periodic_task_interval option is removed
since this doc is really about the FilterScheduler, and the
periodic task interval is only used by the CachingScheduler to
cache and refresh hosts, something the FilterScheduler doesn't do.
The note about service_down_time is already covered in the help
text for the periodic_task_interval option.
- Removed a broken (and oddly placed) link to the block storage
docs; it's unclear why the compute scheduler docs need to randomly
link to the block storage docs for schedluing (maybe that was
super legacy from the nova-volume days).
- Fixed a broken link to the 'evacuate instances' docs.
This change does not get into details for the individual filters
or weighers, only the overview and filter scheduler description.
