Due to lack of GPFS path ('/usr/lpp/mmfs/bin/') export, driver
is not able to find the GPFS commands causing the initialization
failure.
With this patch, GPFS will be able to run all GPFS commands
irrespective of GPFS path export.

Added support for manage/unmanage in GPFS NFS driver.
This patch added functions that allow share on Spectrum Scale
node to be managed by OpenStack if existing fileset is an
independent fileset and doesn't have any NFS export
over the fileset path. Also, share can be unmanaged from
OpenStack but still left in Spectrum Scale cluster.

Use looser error code checking and add a verify
after deny access so that the call will succeed
whenever it can be confirmed that the access no
longer exists.
This fixes a variety of situations where previously
a return code of 1 while attempting to remove access
would cause the manila access rule to get stuck while
the actual client access export was removed or never
existed.

Fix GPFS KNFS allow/deny access so that it does not reuse
the ssh prefix when looping through NFS server commands for
allow and deny access.
This fixes GPFS KNFS allow/deny access incorrect behavior
when multiple NFS servers are configured (gpfs_nfs_server_list)
and any of the servers are remote (except the last one).

Several bugs are caused by an error code and
exception raised when a path has no NFS exports.
Use the machine-readable mmnfs export list command
(the -Y option) which does not cause an exception
when checking for exports.

The Manila test module uses a class called StubOutForTesting, which
is an awkward holdover from when the unit tests were using Mox.
Alex wrote a more elegant and capable mocker method,
manila.test.TestCase.mock_object, in the Cinder project which we
have now added to Manila. So to remove the duplicate functionality
and legacy code, all references to self.stubs.Set() in the Manila
tests should be replaced with self.mock_object() and any related
dead code should be removed.

Due to unclear meanings of existing names for share drivers modes it was
decided to replace string driver modes with boolean value, since we have only
two possible values that will clearly say what it used for by name of opt.
This replacement includes following changes:
- String opt 'share_driver_mode' is replaced with
bool opt 'driver_handles_share_servers'. New bool opt does not have
default value and should be defined explicitly.
- Class ShareDriver (parent class for share drivers) now expects additional
argument 'driver_handles_share_servers' which is mandatory and should be
provided by child classes. Expected values are boolean or tuple/list/set of
booleans that says what modes are supported. Above new config opt will be
compared to these.
- Update interfaces 'setup_server' and 'teardown_server' of class ShareDriver.
These interfaces now consider driver modes and call new additional private
methods only when driver is enabled to mode with share servers handling.
These new private methods are '_setup_server' and '_teardown_server', they
should be redefined by child classes when share servers should be handled by
Manila.
- To get know current driver mode within child classes just call property
'driver_handles_share_servers'. It can not be changed by child classes and
returns value that is set by config opt with same name.
- Remove methods 'setup_server' and 'teardown_server' from all share drivers,
that do not support handling of share servers.
- Rename methods 'setup_server' and 'teardown_server' to appropriate
private methods for drivers that do support handling of share servers.
- Update unit tests related to all changed places.
- Make Devstack set new mandatory bool opt.

Driver mode functionality was implemented to be able to specify how
driver should work and filter backends scheduling share creation based on this.

Supporing GPFS exports over kernel NFS and Ganesha NFS
Supporting following Manila functionality:
1. Create, List, Delete Shares
2. Create, List, Delete Share Snapshots
3. Create Share from a Share Snapshot
4. Allow, Deny access to a share based on IP
Supports, local and remote GPFS nodes to the Manila service node,
in a GPFS cluster
Limitation:
1. While using remote GPFS node, with Ganesha NFS, 'gpfs_private_key'
for remote login to the GPFS node must be specified and there must be
a passwordless authentication already setup between the Manila and the
remote GPFS node.
