Dell: Added verify cert option for REST calls

This simply makes dell_sc_verify_cert a cinder.conf option

Complete switch to snapshot objects
The following patch switches the remainder of cinder internals
to use snapshot object instead of direct db calls. Note that
db calls within cinder drivers were not switched over. This
is left to driver maintainers to do themselves and to
properly test out the changes on their hardware.
Also, note that there are three occurrences of
db.snapshot_update and one of db.snapshot_destroy left in
cinder/volume/manager.py. This is intentional because
driver.create_cgsnapshot and driver.delete_cgsnapshot returns
a list of snapshot dicts. Each driver needs to switched over
occurences of db.snapshot_get_all_for_cgsnapshot() to
SnapshotList.get_all_for_cgsnapshot() in create_cgsnapshot
and delete_cgsnapshot. Once each driver has done so, a follow
up patch can be created to remove db.snapshot_update and
db.snapshot_destroy in cinder/volume/manager.py. There are
bugs filed for these to be fixed -

DriverFilter: don't check volume_backend_name
Currently DriverFilter checks if host_state.volume_backend_name
matches type.extra_specs.volume_backend_name. The same check has
already been done in CapabilitiesFilter and done more thoroughly and
gracefully, for example, volume_backend_name can be a set of names
not limited to one to one match. DriverFilter should just do one
thing, that is evaluating filter_function supplied by backend.
This change removes the volume_backend_name check from DriverFilter
without touching its core function, thus has no impact on existing
documentation because the checking of volume_backend_name is an
undocumented side-effect of this filter. This change also reduces
one warning log to debug log when no filter_function found in
host_state, for the reason it would generate a lot of warning log
for those backends don't supply filter_function.
UpgradeImpact:
DriverFilter had an undocumented side-effect before it evaluates
filter_function - it checked if volume_backend_name in host_state
reported by backend matches volume_backend_name in volume type
extra specs, and if they don't, the backend would fail to pass
the filter. Now that this side-effect has been removed, it
would impact users only under following circumstance: 1) user
enabled DriverFilter but not CapabilitiesFilter; 2) user relied
on DriverFilter to filter backends based on exact match of
'volume_backend_name' in type extra spec. If unfortunately this
is the case for user, enabling CapabilitiesFilter by adding
it to 'scheduler_default_filters' configure option and restart
cinder scheduler service then everything should work just fine.
CapabilitiesFilter actually does a much better job checking
volume_backend_name.

compare with the new volume size for a backend that supports
oversubscription in thin provisioning. The oversubscription

Add standard QoS spec support to cDOT drivers
This commit adds support for standard cinder QoS specs to
NetApp cDOT drivers, alongside our pre-existing support for
externally provisioned QoS policy groups via qualified
extra specs.
Previously, the logic to calculate the LUN ID only considered a single attached
host. Because multiple hosts can be attached to a LUN, the logic needs to
consider multiple hosts. This patchset proposes to choose non-conflicting
LUN IDs across the whole array. This patch first checks for an empty LUN ID
across the array. If it doesn't find one, then it looks for the least used
LUN ID across the whole array.
The value of MAX_LUNS_PER_HOST has been changed here as the range function
iterates from 0 to n-1 LUN IDs. With Eseries backend, a maximum of 256 LUN_IDS
are supported, thus a value of 256 MAX_LUNS_PER_HOST is required.
