Merge pull request #13405 from serathius/downgrade-b 
Implement single node downgrades

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.

etcdserver: configure "expensive" requests duration

etcdserver: configure "expensive" requests duration 
When a unary request takes more than predefined duration, this request
is defined as "expensive" and a warning is printed. The expensive request
duration is hard-coded to 300 ms. It can be not enough for example
for transactions with a lot of operations. The warnings just blow up
the log files and reduce throughput.

This fix allows user to configure the "expensive" request duration.

daf7e0350a etcdserver: remove code duplication from the peer.send func 
During the refactoring process, duplicate logging
of the send buffer overflow event was added.
Each of these log lines logs exactly the same information, the logging
context is sufficient to distinguish the cause.
Additionally, the unnecessary context (in parentheses) in the log
message was removed, which was necessary without the zap context (with
the old logger), but now only confuses.

d9c5e1f0a2 *: Replace internal testutil AssertEqual function in favour of github.com/stretchr/testify/assert.Equals

66752fef2f Represent bucket as object instead of []byte name. 
Thanks to this change:
  - all the maps bucket -> buffer are indexed by int's instead of
string. No need to do: byte[] -> string -> hash conversion on each
access.
  - buckets are strongly typed in backend/mvcc API.

865df75714 Save raftpb.ConfState in the backend. 
This makes (bbolt) backend a full feature snapshot in term of WAL/raft,
i.e. carries:
  - commit : (applied_index)
  - confState

Benefits:
  - Backend will be a sufficient point in time definition sufficient to
start replaying WAL. We have applied_index & confState in consistent
state.
  - In case of emergency a backend state can be used for recovery
