3PAR: Implement v2 replication (managed)
This patch implements the managed side of v2 replication in the HPE
3PAR driver.
Both sync and periodic replication modes are supported. Each
replication_device entry should have a replication_mode value set
to sync|periodic.
A volume type extra_spec value of replication:mode
should also be set. If replication:mode is periodic,
replication:sync_period should be set as well. Which replication_device
entry(s) are used is determined by the value of replication:mode set for
each volume type.
cinder.conf should have the replication config group (3parfcrep)
and at least one other target group (3parfc) as such:

Dynamically Pull Out Option Sections
Previously in the generation of the opts.py file, the option groups
were hard coded. Now, they are pulled out as the lines are parsed.
If a group doesn't already exist in the dictionary it gets added and
then the options are added to the section. If the group already exists,
the options are added to the proper section as you would expect, and if
the options being registered don't have a group, they are added to the
default section.
This patch also moves the check for a non-zero exit code from
oslo-config-generator to the right location in the file. This
logic had been put too late in the file and was not catching
oslo-config-generator failures as it should have been.

Address potential races in SolidFire VAG
While building the initial volume access group solution I realized there were
race conditions present. This patch attempts to address those by being far
more careful during VAG creation and removal. Tracking multiattach volume
detaches around VAG volume removal introduced all sorts of future race
conditions so instead multiattach volumes are treated differently and are only
removed from VAGs on volume removal. Not ideal but it'll get the job done.
Think I covered all the new branches with unit tests. Complexity was introduced
but it should be worth it due to the safety that was also introduced.
The following patch updates migrate_volume,
migrate_volume_completion, and update_migrated_volume
APIs to use volume versionedobjects. Changes were
made to be backwards compatible with older RPC clients.
It only includes changes to the core cinder code.
Changes in the drivers are left to each driver
maintainer to update.
Note that this patch DOES NOT try to use object dot
notation everywhere, since it would increase the
size of the patch. Instead, it will be done in
subsequent patches.
Earlier, quotas used to authenticate to endpoint from not required
option located in keymgr.encryption_auth_url. Now, the required
auth_uri option from config file is used to authenticate to
keystone.

With the current code, it's possible to end up with a zero-size
persistence file (or even corruption of the contents) if the
process gets killed or the system takes a power outage.
Switch to a "write to temp file and rename" model for writing the
persistence file. This will make it more robust against unclean
process termination or unclean system shutdown.

Take into consideration races in XtremIOClient3
When working with FC and xtremio is using XtremIOClient3 on FC's
terminate_connection we can get VolumeBackendAPIException saying a
resource could not be found when we shouldn't.
The cause is that Client3 is open to race conditions on 2 methods,
find_lunmap and num_of_mapped_volumes, where a list of mappings is first
retrieved and then we iterate this list to retrieved additional info on
the mappings.
The race would happen if one of the mappings is removed from the backend
in the time it takes to retrieve the additional info after we have
retrieved the list.
This patch fixes this issue by ignoring any mappings that have been
removed and are now NotFound when retrieving additional information for
a mapping in those 2 methods.
This patch also fixes this kind of race problems on volume creation
since it uses find_lumap method.

Improve metadata update operations
Currently our metadata operations in the DB and the API are less than
optimal, main issues are:
- To update metadata first we get all metadata in the API and add
requested update metadata, then on the DB we retrieve each of the
metadata keys and update one by one contents.
- When deletion of existing keys is requested in the DB we retrieve all
metadata contents and for those that are not in the new metadata we
retrieve the contents from the DB (again) and delete the entry.
This patch changes this so we no longer retrieve metadata in the API,
deletion does not retrieve any metadata from the DB and just makes 1
deletion request to the DB, and for changes we retrieve metadata once
and then issue a bulk change to create new entries and update existing
ones.
To allow atomic state changes across Cinder services we need to
implement a way to easily do compare-and-swap.
This patch adds methods to allow compare-and-swap on DB models and on
Cinder Versioned Objects as well.
Conditions for the compare part of the update can consist of:
- Inclusion: status == 'available'
- Exclusion: status != 'in-use'
- Multi-inclusion: status in ('available', 'error')
- Multi-exclusion: status not in ('attaching', 'in-use')
- Sqlalchemy filters
A complete example of usage would be the compare-and-swap used in volume
delete requests that has to take in consideration not only the status
but the attach and migration status as well as the volume not having
snapshots:
now = timeutils.utcnow()
expected = {'attach_status': db.Not('attached'),
'migration_status': None,
'consistencygroup_id': None}
good_status = ('available', 'error', 'error_restoring',
'error_extending')
if not force:
expected.update(status=good_status)
# Volume cannot have snapshots if we want to delete it
filters = [~sql.exists().where(models.Volume.id ==
models.Snapshot.volume_id)]
It can also be specified whether to save already dirtied fields from the
objects or not and by default (if no expected_values argument is
provided) it will make sure that the entry in the DB has the same values
as the objects we are saving.
We can select values based on conditions using Case objects in the
'values' argument. For example:
Exclusion and multi-exclusion will handle, by default, NULL values like
Python does instead of like SQL does, so NULL values will be considered
different than any non NULL values. That way if we search for something
not equal to 1 we will also get NULL values.
WARNING: SQLAlchemy does not allow selecting order of SET clauses, so
for now we cannot do things like
{'previous_status': model.status, 'status': 'retyping'}
because it will result in both previous_status and status being set to
'retyping'. Issue has been reported [1] and a patch to fix it [2] has
been submitted.
