3de5e221a8 tests: Fix cluster version and downgrade request timeout 
Returning nil means that raft.Trigger was not called, causing member to
wait infinitly for response for response on raft request.

7d10899d7f server: Require either cluster version v3.6 or --experimental-enable-lease-checkpoint-persist to persist lease remainingTTL 
To avoid inconsistant behavior during cluster upgrade we are feature
gating persistance behind cluster version. This should ensure that
all cluster members are upgraded to v3.6 before changing behavior.

To allow backporting this fix to v3.5 we are also introducing flag
--experimental-enable-lease-checkpoint-persist that will allow for
smooth upgrade in v3.5 clusters with this feature enabled.

f5d71fa389 server: Detect when WAL includes unapplied cluster version set to higher version 
This is because etcd v3.5 will panic when it encounters
ClusterVersionSet entry with version >3.5.0. For downgrades to v3.5 to
work we need to make sure this entry is snapshotted.

758fc0f8ad server: Depend only on cluster version to detect downgrade 
Problem with old code was that during downgrade only members with
downgrade target version were allowed to join. This is unrealistic as
it doesn't handle any members to disconnect/rejoin.

*: move from io/ioutil to io and os packages 
The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

923f0aa3e7 etcdserver: Expose metrics with all known peers 
To make it possible to alert on misconfigured etcd clusters that have
missing/superfluous peers, expose the list of peers as a metric.
This metric can, for example, be compared to the control-plane nodes of
a kubernetes cluster.
