This patch adds the ability to run `docker stats` w/o arguments and get
statistics for all running containers by default. Also add a new
`--all` flag to list statistics for all containers (like `docker ps`).
New running containers are added to the list as they show up also.
Add integration tests for this new behavior.
Docs updated accordingly. Fix missing stuff in man/commandline
reference for `docker stats`.

Currently, we get the network stats each time per subscriber, causing a
high load of cpu when there are several subscribers per container.
This change makes the daemon to collect once and publish N times, where N is the
number of subscribers per container.

This fixes a bug introduced in #15786:
* if a pre-v1.20 client requested docker stats, the daemon
would return both an API-compatible JSON blob *and* an API-incompatible JSON
blob: see https://gist.github.com/donhcd/338a5b3681cd6a071629

Although having a request ID available throughout the codebase is very
valuable, the impact of requiring a Context as an argument to every
function in the codepath of an API request, is too significant and was
not properly understood at the time of the review.
Furthermore, mixing API-layer code with non-API-layer code makes the
latter usable only by API-layer code (one that has a notion of Context).
This reverts commit de41640435, reversing

This PR adds a "request ID" to each event generated, the 'docker events'
stream now looks like this:
```
2015-09-10T15:02:50.000000000-07:00 [reqid: c01e3534ddca] de7c5d4ca927253cf4e978ee9c4545161e406e9b5a14617efb52c658b249174a: (from ubuntu) create
```
Note the `[reqID: c01e3534ddca]` part, that's new.
Each HTTP request will generate its own unique ID. So, if you do a
`docker build` you'll see a series of events all with the same reqID.
This allow for log processing tools to determine which events are all related
to the same http request.
I didn't propigate the context to all possible funcs in the daemon,
I decided to just do the ones that needed it in order to get the reqID
into the events. I'd like to have people review this direction first, and
if we're ok with it then I'll make sure we're consistent about when
we pass around the context - IOW, make sure that all funcs at the same level
have a context passed in even if they don't call the log funcs - this will
ensure we're consistent w/o passing it around for all calls unnecessarily.

For now docker stats will sum the rxbytes, txbytes, etc. of all
the interfaces.
It is OK for the output of CLI `docker stats` but not good for
the API response, especially when the container is in sereval
subnets.
It's better to leave these origianl data to user.

- some method names were changed to have a 'Locking' suffix, as the
downcased versions already existed, and the existing functions simply
had locks around the already downcased version.

Replaced github.com/docker/libcontainer with
github.com/opencontainers/runc/libcontaier.
Also I moved AppArmor profile generation to docker.
Main idea of this update is to fix mounting cgroups inside containers.
After updating docker on CI we can even remove dind.

Adds a `stream` query param to the stats API which allows API users to
only collect one stats entry and disconnect instead of keeping the
connection alive to stream more stats.
Also adds a `--no-stream` flag to `docker stats` which does the same
