Make sure that WithPrefix correctly set the flag, and add test.
Also, add test for WithFromKey.

Currently the max size of each WAL entry is hard coded as 10MB. If users
set a value > 10MB for the flag --max-request-bytes, then etcd may run
into a situation that it successfully processes a big request, but fails
to decode it when replaying the WAL file on startup.
On the other hand, we can't just remove the limitation, because if a
WAL entry is somehow corrupted, and its recByte is a huge value, then
etcd may run out of memory. So the solution is to restrict the max size
of each WAL entry as a dynamic value, which is the remaining size of
the WAL file.

The FileReader interface is the wrapper of io.Reader. It provides
the fs.FileInfo as well. The FileBufReader struct is the wrapper of
bufio.Reader, it also provides fs.FileInfo.

Usually the consistent_index should be greater than the index of the
latest snapshot with suffix .snap. But for the snapshot coming from the
leader, the consistent_index should be equal to the snapshot index.
Downstream users of etcd experience build issues when using dependencies
which require more recent (incompatible) versions of opentelemetry. This
commit upgrades the dependencies so that downstream users stop
experiencing these issues.
When a user sets up a Mirror with a restricted user that doesn't have
access to the `foo` path, we will fail to get the most recent revision
due to permissions issues.
With this change, when a prefix is provided we will get the initial
revision from the prefix rather than /foo. This allows restricted users
to setup sync.
humanize.Time() drops precision resulting in some events reporting they took
"now" time to complete. Using time.Duration.String() results in accurate
duration being reported.
Fixes#13905
The code now ensures that each of the test is running in its own directory as opposed to shared os.tempdir.

The reason was that the path exceeded 108 chars (that is too much for socket).
In the mitigation we first change chroot (working directory) to the tempDir... such the path is 'local'.
This change is to ensure that all members returned during the client's
AutoSync are started and are not learners, which are not valid
etcd members to make requests to.
The ClientConfig is a fully declarive configuration, so it makes more
sense to rename it to ConfigSpec. It can also mitigate the confusion
between Config and ClientConfig.
