'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.

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.

To create a share with protocol CIFS it is mandatory to add a security
service to the share network beforehand. If this is forgotten the share
ends up in error. Validate the security service association based on
share protocol from given driver. Raise invalid request exception if
needed association between share_network and security_service is
missing for given driver e.g. ONTAP.

Closes-bug: #1652379
This patch enables the creation of a share from snapshot
specifying another pool or backend. In the scheduler, a
new filter and weigher were implemented in order to consider
this operation if the backend supports it. Also, a new
field called 'progress' was added in the share and share
instance. The 'progress' field indicates the status
of the operation create share from snapshot (in percentage).
Finally, a new periodic task was added in order to constantly
check the share status.

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).
