When online_data_migrations raise exceptions, nova/cinder-manage catches
the exceptions, prints fairly useless "something didn't work" messages,
and moves on. Two issues:
1) The user(/admin) has no way to see what actually failed (exception
detail is not logged)
2) The command returns exit status 0, as if all possible migrations have
been completed successfully - this can cause failures to get missed,
especially if automated
This change adds logging of the exceptions, and introduces a new exit
status of 2, which indicates that no updates took effect in the last
batch attempt, but some are (still) failing, which requires intervention.

This adds a few more things to the upgrade checks
reference docs after getting questions about it
during the Stein release goal implementation from
other project teams:
1. Notes the high level set of steps for upgrading
nova in grenade and where nova-status fits into
that sequence.
2. Links to the oslo.upgradecheck library which
didn't exist when the original document was
written.
3. Adds a FAQs section with Q&A for several things
that have come up during the Stein release goal.

This patch implements live migration of instances across compute nodes.
Each compute node must be managing a cluster in the same vCenter and ESX
hosts must have vMotion enabled [1].
If the instance is located on a datastore shared between source
and destination cluster, then only the host is changed. Otherwise, we
select the most suitable datastore on the destination cluster and
migrate the instance there.

The scheduler_default_filters option is deprecated in favor of

The placement API version 1.28 introduced consumer generation as a way
to make updating allocation safe even if it is done from multiple
places.
This patch changes delete_allocation_for_instance to use PUT
/allocations instead of DELETE /allocations to benefit from the consumer
generation handling.
In this patch the report client will GET the current allocation of the
instance including the consumer generation and then try to PUT an empty
allocation with that generation. If this fails due to a consumer
generation conflict, meaning something modified the allocation of the
instance in between GET and PUT then the report client will raise
AllocationDeleteFailed exception. This will cause that the instance
goes to ERROR state.
This patch only detects a small portion of possible cases when
allocation is modified outside of the delete code path. The rest can
only be detected if nova would cache at least the consumer generation
of the instance.
To be able to put the instance state to ERROR the instance.destroy()
call is moved to the end to of the deletion call path. To keep the
instance.delete.end notification behavior consistent with this move
(e.g. deleted_at field is filled) the notification sending needed to
be moved too.

This adds some background, guidelines and structural
notes on writing nova-status upgrade checks.
This is intentionally written with some potentially
redundant information or nova developers as it's
also meant to be consumed outside nova as part of the
community-wide "upgrade-checkers" goal for Stein [1].

The docs for AggregateMultiTenancyIsolation were misleading in that
tenants are not restricted to hosts only in a tenant-isolated
aggregate. It's the opposite: hosts in the tenant-isolated aggregate
are only available for tenants configured for that aggregate.
This fixes the docs including an example for clarification, and also
adds a functional test to show the behavior of the filter.

Change I1a1143ddf8da5fb9706cf53dbfd6cbe84e606ae1 in Ocata
deprecated the libvirt.live_migration_progress_timeout
and disabled it by default. This change updates the config
option help to refer to the bug so people don't have to hunt
for it via git history, and also touches up the admin docs.
In the one doc, mention of the option is removed altogether
because it basically says, "here is a loaded gun, but don't
use it!". It's better to just not mention the option at all.

Scheduler hints are not really documented very well at all except
for being mentioned per scheduler filter in the admin configuration
guide, nor are they documented within relation to flavor extra
specs which are both used for impacting scheduling decisions and
are choices that a deployer has to make based on how they configure
their cloud.
This change adds a document about scheduler hints and how they are
similar to and different from flavor extra specs, including end
user discoverability and interoperability, and thoughts on which
should be used if writing a custom scheduler filter.
The TODO in the API guide is also resolved by linking to this
document.
