On a ubuntu 15.04 machine with apparmor_parser version 2.10 I get
```
Syntax Error: Unknown line found in file:
/etc/apparmor.d/docker-engine line: 26
```
when running `aa-complain /etc/apparmor.d/docker-engine`.
It's super weird because ipc is documented in the apparmor manual, but it
doesnt seem to be working at all. Tested on a few servers.

Split env resolving into two phases. The first phase is to expand the paths
of env_files, which is done before merging extends. Once all files are merged
together, the final phase is to read the env_files and use them as the base
for environment variables.

Docker daemon uses kv-store as the host-discovery backend.
Discovery module tracks the liveness of a node through a simple
keepalive mechanism. The keepalive mechanism depends on every
node performing heartbeat by registering itself with the discovery
module (via KV-Store Put operation). And for every Put operation,
the discovery module in all other nodes will receive a Watch
notification. That keeps the node alive.
Any node that fails to register itself within the TTL timer is
considered dead and removed from the discovery database.
The default timer (heartbeat = 20 seconds & ttl = 60 seconds)
works fine for small clusters. But for large clusters, these
default timers are extremely aggressive and that causes high CPU
& most of the processing is spent managing the node discovery
and that impacts normal daemon operation.
Hence we need a way to make the discovery ttl and heartbeat
configurable. As the cluster size grows, the user can change
these timers to make sure the daemon scales.

These changes were made as part of https://github.com/docker/docker/pull/17478
but inadvertently added to the v1.21 API version.
Also added a short description to the API changelog.

Our tooling used to convert Markdown to HTML doesn't
properly handle '|' symbols embeded in code blocks
inside a table.
Changed the table to a plain HTML table as a workaround.
Also fixed indentation levels of two code examples.
