WaitStop, if container is restarted too quickly, wait won't have chance

This fix addresses an issue where including the `{{.Size}}` format
field in conjunction with `docker ps --format`, without the `--size`
flag, would not correctly display the size of containers.
This is done by doing a check on the custom format string, and setting
the size flag on the options struct if the field is found. This struct
gets passed to the engine API which then generates the correct query.
An integration test is included which runs `docker ps --format "table
{{.Size}}"` without `--size`, and checks that the returned output is
not `0 B`.
Fixes#21991
As suggested by @cpuguy83, a parser is implemented to process the format
string as a template, and then traverses the template tree to determine
if `.Size` was called.
This was then reworked by making use of template execution with a
pre-processor struct that will set the `--size` option if the template
calls for the field.
The pre-processor now also sets a boolean in the context passed to the
writer. There is an integration test for this that calls `docker ps
--size --format "{{.Size}}"` and then checks that `size: {{.Size}}` is
not appended, as it would with previous behavior.
Finally, a change was made to the formatter to not automatically
add a `{{.Size}}` if a custom format is provided.

This fix tries to address the issue raised in #23055.
Currently `docker search` result caps at 25 and there is
no way to allow getting more results (if exist).
This fix adds the flag `--limit` so that it is possible
to return more results from the `docker search`.
Related documentation has been updated.
Additional tests have been added to cover the changes.

This PR adds support for user-defined health-check probes for Docker
containers. It adds a `HEALTHCHECK` instruction to the Dockerfile syntax plus
some corresponding "docker run" options. It can be used with a restart policy
to automatically restart a container if the check fails.
The `HEALTHCHECK` instruction has two forms:
* `HEALTHCHECK [OPTIONS] CMD command` (check container health by running a command inside the container)
* `HEALTHCHECK NONE` (disable any healthcheck inherited from the base image)
The `HEALTHCHECK` instruction tells Docker how to test a container to check that
it is still working. This can detect cases such as a web server that is stuck in
an infinite loop and unable to handle new connections, even though the server
process is still running.
When a container has a healthcheck specified, it has a _health status_ in
addition to its normal status. This status is initially `starting`. Whenever a
health check passes, it becomes `healthy` (whatever state it was previously in).
After a certain number of consecutive failures, it becomes `unhealthy`.
The options that can appear before `CMD` are:
* `--interval=DURATION` (default: `30s`)
* `--timeout=DURATION` (default: `30s`)
* `--retries=N` (default: `1`)
The health check will first run **interval** seconds after the container is
started, and then again **interval** seconds after each previous check completes.
If a single run of the check takes longer than **timeout** seconds then the check
is considered to have failed.
It takes **retries** consecutive failures of the health check for the container
to be considered `unhealthy`.
There can only be one `HEALTHCHECK` instruction in a Dockerfile. If you list
more than one then only the last `HEALTHCHECK` will take effect.
The command after the `CMD` keyword can be either a shell command (e.g. `HEALTHCHECK
CMD /bin/check-running`) or an _exec_ array (as with other Dockerfile commands;
see e.g. `ENTRYPOINT` for details).
The command's exit status indicates the health status of the container.
The possible values are:
- 0: success - the container is healthy and ready for use
- 1: unhealthy - the container is not working correctly
- 2: starting - the container is not ready for use yet, but is working correctly
If the probe returns 2 ("starting") when the container has already moved out of the
"starting" state then it is treated as "unhealthy" instead.
For example, to check every five minutes or so that a web-server is able to
serve the site's main page within three seconds:
HEALTHCHECK --interval=5m --timeout=3s \
CMD curl -f http://localhost/ || exit 1
To help debug failing probes, any output text (UTF-8 encoded) that the command writes
on stdout or stderr will be stored in the health status and can be queried with
`docker inspect`. Such output should be kept short (only the first 4096 bytes
are stored currently).
When the health status of a container changes, a `health_status` event is
generated with the new status. The health status is also displayed in the
`docker ps` output.

Since 1.9, the following short variant options have been
deprecated in favor of their long variants:
`docker run -c (--cpu-shares)`
`docker build -c (--cpu-shares)`
`docker create -c (--cpu-shares)`
`docker update -c (--cpu-shares)`
However, `-c` is still widely used and is considered as
a convenient option for swarm (see #16271).
This fix undeprecated the command line short
variant options of `-c` and updated the deprecated.md.

… and refactor a little bit some daemon on the way.

`daemon.go` is getting pretty big.
- `registry.Service` is now an interface (allowing us to decouple it a
little bit and thus unit test easily).
- Add some unit test for `SearchRegistryForImages`.
- Use UniqueExactMatch for search filters
- And use empty restore id for now in client.ContainerStart.

The jsonlog logger currently allows specifying envs and labels that
should be propagated to the log message, however there has been no way
to read that back.
This adds a new API option to enable inserting these attrs back to the
log reader.
With timestamps, this looks like so:
```
92016-04-08T15:28:09.835913720Z foo=bar,hello=world hello
```
The extra attrs are comma separated before the log message but after
timestamps.
Without timestaps it looks like so:
```
foo=bar,hello=world hello
```

This fix tries to fix the discrepancy between `docker stats` and
`docker run` where `docker run` uses RAMInBytes for all memory
related inputs but `docker stats` uses HumanSize for all memory
related outputs.
To be consistent, `docker stats` needs to use BytesSize for all
memory related outputs to conform to RAMInBytes in `docker run`.
This fix addresses this issue. As BytesSize is used, the test
cases needs to be adjusted to match `KiB/MiB/GiB` instead of
`KB/MB/GB`.
The documentation has also been updated.
This fix fixes#21765.
