'reserved_share_extend_percentage' backend config option allows Manila
to consider different reservation percentage for share extend
operation. With this option, under existing limit of
'reserved_share_percentage', we do not want user to create new share if
limit is hit, but allow user to extend existing share.

compatibility library) in favor of py3 syntax.

This config option allows different value for reservation percentage,
mostly useful on the platforms, where shares can only be created from
the snapshot on the host where snapshot was taken. The lower value of
this config option against existing (reserved_share_percentage) allows
to create shares from the snapshot on the same host up to a higher
threshold even though non-snapshot/regular share create fails.
In case this config option is not set, the shares created from snapshot
will use reservation percentage value set in 'reserved_share_percentage'.
This will be useful for users who want to keep same reservation percentage
for both non-snapshot/regular and snapshot shares.

1. Try parse share_backend_id from export path in case
it is managed share.
2. Try to take snapshot id from 'provider_location' in case
this is managed snapshot
3. Try to get share server name from property 'identifier'
first in case this is managed share server
4. Add property 'provider_location' when creating snapshot

Implement revert to snapshot support for Dell EMC Unity driver.
Change-Id: I3a4da4a506ae4c2dbcd97207121ce19ecfb98043
Implements: unity-revert-to-snapshot
Major changes:
* Support to create/delete/extend/access NFS and CIFS share/snapshot
in the IPv6 network which created by Neutron
* Support to connect Unity management interface using IPv6 address
Change-Id: I590d569c6fe1a0f8b146bec9c74513269b8358f4
Implements: blueprint unity-manila-ipv6-support
The enhancement includes:
1. Creates tenant for each vlan on the unity system. So that the nas
server in different vlan will have isolated IP address space.
2. Select the appropriate port on the system to create interface based
on MTU.
3. Remove the option unity_server_container (the old
emc_nas_server_container option) to enable the storage processors load
balance and the auto-selection of ports (by mtu).
