As Eugene mentioned in his reply, this is not expected to break backward
compatibility, and in fact, your old packaging should continue to work
fine.  The only change committed was a change to the example, as it is now
valid to put the config in either location, but telling users to put it in
quantum.conf seemed more straightforward.

The l3-agent no longer requires keystone auth, as it uses RPC to fetch this
data instead.

The metadata_agent.ini is actually for a new agent that is un-related to
the keystone changes.  This is new functionality in Grizzly to handle
metadata with overlapping IP addresses.   We have a doc bug tracking
details on how to install this agent (
https://bugs.launchpad.net/openstack-manuals/+bug/1099573) but in the
meantime you could probably look at devstack or the Ubuntu packages if
you're interested in how it is used + configured).
