as of Ubuntu Yakkety, dirmngr is now in a separate
package (see https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1634464)
this patch updates the install script to install
the dirmngr package if it's not installed.

This reduces allocs and bytes used per log entry significantly as well
as some improvement to time per log operation.
Each log driver, however, must put messages back in the pool once they
are finished with the message.

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.
Related docs has been updated.

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>
</div>
</body>
</html>
```
This fix fixes 28176.
