The list of supported annotations for Consul service mesh were moved
from /docs/k8s/connect to /docs/k8s/annotations-and-labels in PR
#12323.
This commit updates various across the site to point to the new
URL for these annotations.
It can only work if there is a running service instance in the local DC,
so this is a bit misleading, since failover and redirects are typically
used when there is not an instance in the local DC.
Initially we were loading every potential upstream address into Envoy
and then routing traffic to the logical upstream service. The downside
of this behavior is that traffic meant to go to a specific instance
would be load balanced across ALL instances.
Traffic to specific instance IPs should be forwarded to the original
destination and if it's a destination in the mesh then we should ensure
the appropriate certificates are used.
This PR makes transparent proxying a Kubernetes-only feature for now
since support for other environments requires generating virtual IPs,
and Consul does not do that at the moment.
