This allows the user to set a logging mode to "blocking" (default), or
"non-blocking", which uses the ring buffer as a proxy to the real log
driver.
This allows a container to never be blocked on stdio at the cost of
dropping log messages.
Introduces 2 new log-opts that works for all drivers, `log-mode` and
`log-size`. `log-mode` takes a value of "blocking", or "non-blocking"
I chose not to implement this as a bool since it is difficult to
determine if the mode was set to false vs just not set... especially
difficult when merging the default daemon config with the container config.
`log-size` takes a size string, e.g. `2MB`, which sets the max size
of the ring buffer. When the max size is reached, it will start
dropping log messages.

This fix tries to improve the display of `docker service ls`
and adds `--format` flag to `docker service ls`.
In addition to `--format` flag, several other improvement:
1. Updates `docker stacks service`.
2. Adds `servicesFormat` to config file.

This fix tries to address the issue raised in 28176 where
text frame was used in websocket attach endpoint. In case
the data send out contains non utf8 data, the connection
will be closed in certain browsers, e.g., Safari.
This fix address the issue by change `PayloadType` to `BinaryFrame`.
This fix is tested manually with Safari. The docker daemon is inside a Linux Virtual Machine.
Create a container with:
```
docker run -itd --name websocket busybox sh -c "while true; do echo -e 'he\\xc3\\x28o'; sleep 5; done"
```
Use the following url (172.16.66.128:2375 is the tcp address of the daemon):
```
file:///websocket.html?url=ws://172.16.66.128:2375/v1.25/containers/websocket/attach/ws?logs=1&stderr=1&stdout=1&stream=1&stdin=1
```
and the following html:
```
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Websocket</title>
<script type="text/javascript">
function DockerWebSocket() {
if ("WebSocket" in window) {
console.log("WebSocket is supported by Browser...")
// Remove '?url=' prefix
url = window.location.search.replace(/^(\?url=)/,"");
console.log("URL ["+url+"]...");
var ws = new WebSocket(url);
ws.onopen = function() {
console.log("Connection is opened...");
};
ws.onclose = function() {
console.log("Connection is closed...");
};
ws.onmessage = function (e) {
if (typeof e.data === "string") {
alert("WebSocket received text message ["+e.data+"]!")
} else {
console.log("Message is received...")
var blobReader = new FileReader();
blobReader.onload = function(event) {
console.log(JSON.stringify(blobReader.result))
};
blobReader.readAsText(e.data)
console.log("Message complete...")
}
};
} else {
alert("WebSocket is not supported by Browser!");
}
}
</script>
</head>
<body>
<div>
<a href="javascript:DockerWebSocket()">Run DockerWebSocket</a>

This fix tries to address the issue raised in 29972 where
it was not possible to specify `--read-only` for `docker service create`
and `docker service update`, in order to have the container's root file
system to be read only.
This fix adds `--read-only` and update the `ReadonlyRootfs` in `HostConfig`
through `service create` and `service update`.

This fix tries to address the enhancement proposal raised in
27178 for filtering based on published or exposed ports of
`docker ps --filter`.
In this fix, two filter options, `publish` and `expose` have
been added to take either `<port>[/<protocol>]` or `<from>-<to>[/<protocol>]`
and filtering on containers.
An integration test has been added to cover the changes.
This fix fixes 27178.

This fix made several updates:
1. Update opts.MemBytes so that default value will not show up.
The reason is that in case a default value is decided by daemon,
instead of client, we actually want to not show default value.
2. Move `docker run/create/build` to use opts.MemBytes for `--shm-size`
This is to bring consistency between daemon and docker run
3. docs updates.

Commit ed13c3abfb added flags
for Docker Content Trust. Depending on the `verify` boolean,
the message is "Skip image verification", or "Skip image signing".
"Signing" is intended for `docker push` / `docker plugin push`.
During the migration to Cobra, this boolean got flipped for
`docker push` (9640e3a451),
causing `docker push` to show the incorrect flag description.
This patch changes the flags to use the correct description
for `docker push`, and `docker plugin push`.
To prevent this confusion in future, the boolean argument
is removed, and a `AddTrustSigningFlags()` function is added.

This fix tries to address the enhancement discussed in 28735 to add
`--format` for the output of `docker plugin ls`.
This fix
1. Add `--format` and `--quiet` flags to `docker plugin ls`
2. Convert the current implementation to use `formatter`, consistent with
other docker list commands.
3. Add `pluginsFormat` for config.json.
Related docs has been updated.
Several unit tests have been added to cover the changes.
This fix is related to 28708 and 28735.
