Servers should always be upgraded before agents, but generally this
isn't required because things are compatible between versions. In this
case we're OK with failing closed if the user upgrades out of order, but
we should give a clearer message about what steps are required to fix
the issue.

We have had a couple issues with newer agents not working with old
servers or vice versa. Add a CI test to test variations on
uplevel/downlevel server/agent against latest, stable, and the previous
branch.

* Collect IPs from all pods before deciding to use internal or external addresses

@Taloth correctly noted that the code that iterates over ServiceLB pods
to collect IP addresses was failing to add additional internal IPs once
the map contained ANY entry from a previous node. This may date back to
when ServiceLB used a Deployment instead of a DaemonSet, so there was
only ever a single pod.

The new behavior is to collect all internal and external IPs, and then
construct the address list of a single type - external if there are any,
otherwise internal.
