This is a first step towards moving all code related to local
manipulation of images into a cleanly separated subsystem,
accessible via a stable set of commands in the engine API.
`graph.TagStore` now implements `engine.Installer`. For now, it
is installed by `Server.InitServer`, along with all other Server
commands. However this will change in future patches.
`graph.TagStore.Install` registers the following commands:
* `image_set` creates a new image and stores it locally.
* `image_get` returns information about an image stored locally.
* `image_tag` assigns a new name and tag to an existing image.
These commands are a pre-requisite for moving 'push' and 'pull'
out of `Server`.

When sending a new job to a `engine.Sender`, the corresponding
`engine.Receiver` will receive that job with its environment preserved.
Previously the job name, arguments and streams were preserved but the
env was lost.

* `Env.MultiMap` returns the contents of an Env as `map[string][]string`
* `Env.InitMultiMap` initializes the contents of an Env from a `map[string][]string`
This makes it easier to import and export an Env to other formats
(specifically `beam/data` messages)

This is a convenience for callers which are only interested in one value
per key. Similar to how HTTP headers allow multiple keys per value, but
are often used to store and retrieve only one value.

This introduces a superficial change to the Beam API:
* `beam.SendPipe` is renamed to the more accurate `beam.SendRPipe`
* `beam.SendWPipe` is introduced as a mirror to `SendRPipe`
There is no other change in the beam API.

In the documentation was not mentioned explicitly that VOLUME value
shoud be a valid JSON array. Because of this I spent time to discovering
the problem with my image where I put `VOLUME ['/data']` (with single quotes).
The `['/data']` mount point was parsed and mounted whole as a string without
any errors and warnings.

MongoDB article had some fundemental issues.
- Outdated Dockerfile
- Insufficient / unclear instructions
- Unnecessary comments
- Failed to explain the role of Docker.io
- Did not have a complete Dockerfile sample
- Lacked a "learn more" section / link to Trusted Builds
This update aims to address all these issues with a complete re-write.
It also:
- Corrects the label under which this article is/was listed on the menu

- First run at amending after the initial review process.
- Make the Dockerfile generic.
- Revision.
- Fixes
This renames the goruntime import of the runtime package back to
runtime.

Update restrict.Restrict to both show the error message when failing to mount /dev/null over /proc/kcore, and to ignore "not exists" errors while doing so (for when CONFIG_PROC_KCORE=n in the kernel)
