Nejc Saje b0116dbb22 Use central agent manager's keystone token in discoveries
Currently, EndpointDiscovery creates its own keystone client.
This patch passes an agent-manager reference into the discoveries,
enabling them to reuse the manager's keystone client and possibly
other things in the future.
