46f04b3c15 pkg/adt: add "IntervalTree.Delete" failure case 
Described in https://github.com/etcd-io/etcd/issues/10877.

"black-height" property: Every path from a node to any descendant leaf node must have the same number of black nodes.

465592a718 Documentation/etcd-mixin: Add an alert for down etcd members 
An etcd member being down is an important failure state - while
normal admin operations may cause transient outages to rotate,
when any member is down the cluster is operating in a degraded
fashion. Add an alert that records when any members are down
so that administrators know whether the next failure is fatal.

The rule is more complicated than `up{...} == 0` because not all
failure modes for etcd may have an `up{...}` entry for each member.
For instance, a Kubernetes service in front of an etcd cluster
might only have 2 endpoints recorded in `up` because the third
pod is evicted by the kubelet - the cluster is degraded but
`count(up{...})` would not return the full quorum size. Instead,
use network peer send failures as a failure detector and attempt
to return the max of down services or failing peers. We may
undercount the number of total failures, but we will at least
alert that a member is down.
