Before this patch, a log reader is able to block all log writes
indefinitely (and other operations) by simply opening the log stream and
not consuming all the messages.
The reason for this is we protect the read stream from corruption by
ensuring there are no new writes while the log stream is consumed (and
caught up with the live entries).
We can get around this issue because log files are append only, so we
can limit reads to only the section of the file that was written to when
the log stream was first requested.
Now logs are only blocked until all files are opened, rather than
streamed to the client.

COmmit 0307fe1a0b added
a new `DataPathAddr` property to the swarm/init and swarm/join
endpoints. This property was not yet added to the
documentation.

Description:
1. start a container with restart=always.
`docker run -d --restart=always ubuntu sleep 3`
2. container init process exits.
3. use `docker pause <id>` to pause this container.
if the pause action is before cgroup data is removed and after the init process died.
`Pause` operation will success to write cgroup data, but actually do not freeze any process.
And then docker received pause event and stateExit event from
containerd, the docker state will be Running(paused), but the container
is free running.
Then we can not remove it, stop it , pause it and unpause it.

The name/ID relationships are maintained separately from the memdb and
can be out of sync from any particular memdb snapshot. If a container
does not exist in the memdb, we must accept this as normal and not fail
the listing. This is consistent with what the code used to do before
memdb was introduced.

Recently, it's become necessary to build dynbinaries on certain
distributions, so make it easier for users to build dynbinaries. It
looks like this was just an oversight when we added dynbinary builds.

Before this patch, if the plugin's `config.json` is successfully removed
but the main plugin state dir could not be removed for some reason (e.g.
leaked mount), it will prevent the daemon from being able to be
restarted.
This patches changes this to atomically remove the plugin such that on
daemon restart we can detect that there was an error and re-try. It also
changes the logic so that it only logs errors on restore rather than
erroring out the daemon.
This also removes some code which is now duplicated elsewhere.

If a client is initialized without a specific
version set, version negotiation would not be
functional.
This patch changes the behavior to always
perform version negotation (if called), in
which case the "current" (maximum supported
API version) is used as a default.

If a container doesn't exist in the memdb, First will return nil, not an
error. This should be checked for before using the result.

With debug logging turned on, we currently log the base64-encoded secret
payload.
Change the middleware code to redact this. Since the field is called
"Data", it requires some context-sensitivity. The URI path is examined
to see which route is being invoked.

In some cases a server may return an error on the ping response but
still provide version details. The client should use these values when
available.

Because of argument order to assert, in case of fail, we'll get message
like:
... obtained string = "uid=100(test) gid=101(test)\n"
... expected string = "uid=100(test) gid=101(test) groups=101(test)\n"
But obtained string should be second one, not the first one. And
expected string should be first. Here's sample output from test above:
... Output: before restart 'uid=100(test) gid=101(test)
', after restart 'uid=100(test) gid=101(test) groups=101(test)
It's confusing, because expected order of strings in assertion is
reversed. What goes before restart - should be "expected string" and
what goes after - should be "obtained string".
