Is public filter in image-list

[Iccha Sethi]

It will be good to be able to filter based on public and private images in glance image-list.

Currently it supports only the following:

usage: glance image-list [--name <NAME>] [--status <STATUS>]
                         [--container-format <CONTAINER_FORMAT>]
                         [--disk-format <DISK_FORMAT>] [--size-min <SIZE>]
                         [--size-max <SIZE>] [--property-filter <KEY=VALUE>]
                         [--page-size <SIZE>] [--human-readable]
                         [--sort-key {name,status,container_format,disk_format,size,id,created_at,updated_at}]
                         [--sort-dir {asc,desc}]

    Filter images list by public=True|False

    When running the image-list command the user should have the option
    to list images according to whether or not the image is was set
    to public. A new test is included to verify this behavior.
