Don't raise HTTPForbidden on a multitenant environment

When getting public images in a multi-tenant environment, Swift raises
HTTPForbidden for chuncked images.

Based on swift documentation, rlistings directive turns listings on,
which is the desired behavior in this case.

Fixes bug 1170156

NOTE: Swift guys where consulted about this fix.

Call monkey_patch before other modules are loaded

This patch moves the monkey_patch call into the glance scripts that
needs libs to be monkey_patched. This seems to be a good practice and
has given good results for other projects as well.

This change is needed  to avoid loading / initializing modules
before other libs are patched. For example: logging module.

Call os.kill for each child instead of the process group

The patch sets the process group id to its process id. Note that this
change raises an OSError in Glance's tests because they are run under
Popen and using glance-control, which changes children's session ids and
other parameters. That for, setpgid is inside a try / except and falls
back to 0.

Fixes bug 1068051

NOTE: This issue is not affecting production/stable environments (no comments
related to that have been made) but the issue is there and raises under
certain cases.

The backport is being suggested because this is, most likely, happening
under the hoods without users even noticing it.
