glance_store should copy data files to glance while installed using setup.py

[Abhishek Kekane]

At the moment if you need to configure cinder store of glance in your environment then you need to manually copy rootwrap related files from glance_store/etc/glance to /etc/glance folder.
IMO this should be done by glance_store itself when someone installs glance_store using setup.py file.

    Copy data files to glance upon installation

    At the moment if you need to configure cinder store of glance in your
    environment then you need to mannualy copy rootwrap related files
    from glance_store/etc/glance to /etc/glance folder.

    Added those rootwrap.* related files as data_files in setup.cfg
    which will copies those to /etc/glance on installation.
