The `docker logs` command performed a
client-side check if the container's
logging driver was supported.
Now that we allow the client to connect
to both "older" and "newer" daemon versions,
this check is best done daemon-side.
This patch remove the check on the client
side, and leaves validation to the daemon,
which should be the source of truth.

While looking into `docker stats <c1> <c2> ...` I noticed that
the error output is quite long, especially if there are multiple errors:
```sh
ubuntu@ubuntu:~/docker$ docker stats nofound
: Error response from daemon: No such container: nofound
ubuntu@ubuntu:~/docker$ docker stats nofound foo bar
: Error response from daemon: No such container: nofound, : Error response from daemon: No such container: foo, : Error response from daemon: No such container: bar
```
There are several issues,
1. There is an extra `: ` at the beginning. That is because if container is not found,
the name will not be available from the daemon.
2. Multiple errors are concatenated with `, ` which will be quite long.
This fix:
1. Only prient out the error from daemon.
2. Multiple errors are printed out line by line.
Below is the new output:
```sh
ubuntu@ubuntu:~/docker$ docker stats nofound
Error response from daemon: No such container: nofound
ubuntu@ubuntu:~/docker$ docker stats nofound foo bar
Error response from daemon: No such container: nofound
Error response from daemon: No such container: foo
Error response from daemon: No such container: bar
```

This fix convert DanglingOnly in ImagesPruneConfig to Filters,
so that it is possible to maintain API compatibility in the future.
Several integration tests have been added to cover changes.
This fix is related to 28497.

For previous versions of Docker, `--rm` was handled client side, as such
there was no support in the daemon for it.
Now it is handled daemon side, but we still need to handle the case of a
newer client talking to an older daemon.
Falls back to client-side removal when the daemon does not support it.

This fix is an attempt to address the issue raised in 28339. In
`docker ps`, the formatter needs to expose all fields of `types.Container`
to `preProcessor` so that template could be executed.
This direct exposing is unreliable and could cause issues as user may incorrectly
assume all fields in `types.Container` will be available for templating.
However, the purpose of `preProcessor` is to only find out if `.Size`
is defined (so that opts.size could be set accordingly).
This fix defines `preProcessor` as `map[string]bool` with a func `Size()`.
In this way, any unknown fields will be ignored.
This fix adds several test cases to the existing `TestBuildContainerListOptions`.
This fix fixes 28339.

This adds support to display names or id of container instead of what
was provided in the request.
This keeps the default behavior (`docker stats byname` will display
`byname` in the `CONTAINER` colmun and `docker stats byid` will display
the id in the `CONTAINER` column) but adds two new format directive.

In file `api/types/client.go`, some of the "*Options{}" structs own a
`Filters` field while some else have the name of `Filter`, this commit
will rename all `Filter` to `Filters` for consistency. Also `Filters`
is consistent with API with format `/xxx?filters=xxx`, that's why
`Filters` is the right name.

containers may specify these cgroup values at runtime. This will allow
processes to change their priority to real-time within the container
when CONFIG_RT_GROUP_SCHED is enabled in the kernel. See #22380.
Also added sanity checks for the new --cpu-rt-runtime and --cpu-rt-period
flags to ensure that that the kernel supports these features and that
runtime is not greater than period.
Daemon will support a --cpu-rt-runtime flag to initialize the parent
cgroup on startup, this prevents the administrator from alotting runtime
to docker after each restart.
There are additional checks that could be added but maybe too far? Check
parent cgroups to ensure values are <= parent, inspecting rtprio ulimit
and issuing a warning.

Keeping the current behavior for exec, i.e., inheriting
variables from main process. New variables will be added
to current ones. If there's already a variable with that
name it will be overwritten.
Example of usage: docker exec -it -e TERM=vt100 <container> top

The formatter.ContainerStats struct exposes its Mutex.
This is a bad design and should be fixed.
To fix that, I separated the statistics
attributes from ContainerStats to StatsEntry and
hid the mutex. Notice that the mutex protects both
the `err` field and the statistics attributes.
Then, implemented SetStatistics, SetError, GetStatistics
and GetError to avoid races.
Moreover, to make this less granular, I decided to
replace the read-write mutex with the regular mutex and
to pass a StatsEntry slice to formatter.ContainerStatsWrite
