$namespace = openstack.image.v{1|2}

The subcommand documents for $namespace were hardcoded and thus prone to
drift over time. This commit removes the hardcoded content and uses the
autoprogram-cliff directive to generate them automatically from the
subcommand configuration classes.

Some reorganization happened here. The `image` subcommand name is shared
by image v1 and v2. Previously the hardcoded document had them combined
and interleaved. Attempting to preserve this with autoprogram-cliff
would have required significant additional infrastructure. However,
since most readers care completely about one and not at all about the
other, we instead split the v1 and v2 versions of these commands into
separate pages. In case links to the old pages exist in the wild, they
are preserved, but moved (with redirects) to a hidden directory, and
populated simply with links to the new version-specific generated
documents.

In order to see image sharing membership it is required to additionally
pass member_status filter to API. Otherwise only those with status 'all'
will be returned. Thus adding possibility to see images shared with
project to be approved or rejected.

Only with the admin role you can use the project name with
'image add project'. With the normal member role you have to use the
project id instead. If you try to use the name, you don't receive an
error, but it won't work.

"--community" was added to "image create" and "image set" previously,
but was missed in "image list".

The OpenStack client presently has support to add or remove members
from an image, but no way to list image members.  This patch addreses
this issue.

nova api support parameters like 'name', 'server', 'status',
etc in image-list(). So openstackclient should support this too.

This feature will allow image owners to share images across multiple
tenants/projects without explicitly creating members individually
through the glance API V2. “Community images” will not appear iu
user's default image listings
