object-storage: refactor to use swift devices

Refactor code to use the devices configuration file setting for account,
container, and object servers, dropping mount_path from the fs.conf file, and
constructing new account, container and object server rings.

This removes the next to last set of diffs in the swift diff file. See BZ
870589 (https://bugzilla.redhat.com/show_bug.cgi?id=870589).

The key to the change is the dropping of the pre-built account, container and
object rings, instead providing a script that will generate them for the user
given the gluster volume name in use. In addition, we override the Swift
check_mount() method and replace it with Gluster's which attempts to
"auto-mount" if it is not already mounted.

The following is an enumeration of the changes contained in this refactoring:

    * The refactoring to override the Swift check_mount() involved condensing
      a lot of code, removing redundancies and simplifying methods across a
      number of modules

    * Drop checking the mount point in the low level DiskDir, DiskAccount and
      DiskFile objects now that Swift's normal mount checking is used, and
      enable it by default in the template configuration file

    * Add missing get_container_timestamp() method for DiskAccount objects

    * Fix the plugin RPM spec file to provide the new ring builders, and while
      we were at it, finally fix the over-writing of the configuration files
      on install

    * Bug fixes

        * The monkey patched version of check_object_creation was not working
          correctly due to a missing import of HTTPBadRequest and a bad
          reference to validate_obj_name_component()

        * Only have the utils module import the plugins constraints module for
          the side effect of monkey patching if gluster is enabled

        * Removed the db_file.db file in the tree since it is created on the
          fly

        * Updated 2011 copyright notices to 2012
