  both the follower and leader probing optimization
- fix the log message in stepLeader that previously mixed up the
  log term for the rejection and the index of the append
- improve the test via subtests
- add some verbiage in findConflictByTerm around first index

b757e1bc87 raft: create new probe_and_replicate.txt interactive test 
This commit creates a new probe_and_replicate.txt interactive test. The
test creates a complete Raft log configuration and demonstrates how a
leader probes and replicates to each of its followers. The log
configuration constructed is identical to the one present in Figure 7 of
the raft paper (https://raft.github.io/raft.pdf), which looks like:

```
     1  2  3  4  5  6  7  8  9  10 11 12
n1: [1][1][1][4][4][5][5][6][6][6]
n2: [1][1][1][4][4][5][5][6][6]
n3: [1][1][1][4]
n4: [1][1][1][4][4][5][5][6][6][6][6]
n5: [1][1][1][4][4][5][5][6][7][7][7][7]
n6: [1][1][1][4][4][4][4]
n7: [1][1][1][2][2][2][3][3][3][3][3]
```

Once in this state, we then elect node 1 as the leader and stabilize the
entire raft group. This demonstrates how a newly elected leader probes
for matching indexes, overwrites conflicting entries, and catches up all
followers.

This will be useful to demonstrate the impact of more efficient probing
behavior.

2ae3e82f07 etcdserver/api/etcdhttp: log successful etcd server side health check in debug level 
When we have an external component that checks /health periodically, the
etcd server logs can be quite verbose (e.g., DDOS-ing against insure
etcd health check can lead to disk space full due to large log files).

This change was introduced in #11704.

While we keep the warning logs for etcd health check failures, the
success (or OK) log level should be set to DEBUG.

Fixes #12676

In fact this commit rewrites the functionality to use upstream list of
ciphers instead of checking whether the lists are in sync using ast
analysis.

1) Fix the path for rpc errors
2) The README says 2 types of client errors vs doc mentioning 3
types of client errors. grpc erros should be considered single time
as covered in the README.
