This allows our tests, which all share a containerd instance, to be a
bit more isolated by setting the containerd namespaces to the generated
daemon ID's rather than the default namespaces.
This came about because I found in some cases we had test daemons
failing to start (really very slow to start) because it was (seemingly)
processing events from other tests.

This reverts commit 98fc09128b in order to
keep registry v2 schema1 handling and libtrust-key-based engine ID.
Because registry v2 schema1 was not officially deprecated and
registries are still relying on it, this patch puts its logic back.
However, registry v1 relics are not added back since v1 logic has been
removed a while ago.
This also fixes an engine upgrade issue in a swarm cluster. It was relying
on the Engine ID to be the same upon upgrade, but the mentioned commit
modified the logic to use UUID and from a different file.
Since the libtrust key is always needed to support v2 schema1 pushes,
that the old engine ID is based on the libtrust key, and that the engine ID
needs to be conserved across upgrades, adding a UUID-based engine ID logic
seems to add more complexity than it solves the problems.
Hence reverting the engine ID changes as well.

This changes the default ipc mode of daemon/engine to be private,
meaning the containers will not have their /dev/shm bind-mounted
from the host by default. The benefits of doing this are:
1. No leaked mounts. Eliminate a possibility to leak mounts into
other namespaces (and therefore unfortunate errors like "Unable to
remove filesystem for <ID>: remove /var/lib/docker/containers/<ID>/shm:
device or resource busy").
2. Working checkpoint/restore. Make `docker checkpoint`
not lose the contents of `/dev/shm`, but save it to
the dump, and be restored back upon `docker start --checkpoint`
(currently it is lost -- while CRIU handles tmpfs mounts,
the "shareable" mount is seen as external to container,
and thus rightfully ignored).
3. Better security. Currently any container is opened to share
its /dev/shm with any other container.
Obviously, this change will break the following usage scenario:
$ docker run -d --name donor busybox top
$ docker run --rm -it --ipc container:donor busybox sh
Error response from daemon: linux spec namespaces: can't join IPC
of container <ID>: non-shareable IPC (hint: use IpcMode:shareable
for the donor container)
The soution, as hinted by the (amended) error message, is to
explicitly enable donor sharing by using --ipc shareable:
$ docker run -d --name donor --ipc shareable busybox top
Compatibility notes:
1. This only applies to containers created _after_ this change.
Existing containers are not affected and will work fine
as their ipc mode is stored in HostConfig.
2. Old backward compatible behavior ("shareable" containers
by default) can be enabled by either using
`--default-ipc-mode shareable` daemon command line option,
or by adding a `"default-ipc-mode": "shareable"`
line in `/etc/docker/daemon.json` configuration file.
3. If an older client (API < 1.40) is used, a "shareable" container
is created. A test to check that is added.

Before this commit if "--config-file" wasn't set the daemon would use
the default configuration file which is "/etc/docker/daemon.json".
When attempting to reload the daemon if that file didn't exist
and error message would display.
This behaviour is changed in a way that if the default configuration
file does not exist and no other configuration file is set
the daemon uses an empty configuration which later will be updated
and reloaded using the "reload" function given as an argument in Reload.
However, if the "--config-file" is set and the file is removed
or renamed an error message will be displayed and no reload will be done.
