431adc5878 server: Implement storage downgrades 
By validating if WAL doesn't include any incompatible entries we can
implement storage downgrades.

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.

ff3729c4d5 server: Implement storage schema migration to follow cluster version change and panic if unknown storage version is found 
Storage version should follow cluster version. During upgrades this
should be immidiate as storage version can be always upgraded as storage
is backward compatible. During downgrades it will be delayed and will
require time for incompatible changes to be snapshotted.

As storage version change can happen long after cluster is running, we
need to add a step during bootstrap to validate if loaded data can be
understood by migrator.
