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 is part of the discussion in 28199 about using
`truncate` to replace `--no-trunc`.
As part of the fix, a new function `truncate` has been
added for Go templates so that it is possible to use
```
docker stack services --format "{{truncate .ID 5}}: {{.Mode}} {{.Replicas}}"
```
to show truncated ID.
A unit test has been added.
This fix is related to 28199.

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`.
Related docs has been updated.
Integration test has been added.
This fix fixes 29972.

Added an apparmorEnabled boolean in the Daemon struct to indicate if AppArmor is enabled or not. It is set in NewDaemon using sysInfo information.
