Simplified the docs on how to set environment variables in a
container. Makes it clear that you have three options, and how
to use them.

Command name should be a H1
Only Description, Examples, and Related Commands should be H2
Changed 'Related information' heading to 'Related commands' since 99% it is only linking commands
Added some examples where relevant

This fix made several updates:
1. Update opts.MemBytes so that default value will not show up.
The reason is that in case a default value is decided by daemon,
instead of client, we actually want to not show default value.
2. Move `docker run/create/build` to use opts.MemBytes for `--shm-size`
This is to bring consistency between daemon and docker run
3. docs updates.

This fix is a follow up to #27567 based on:
https://github.com/docker/docker/pull/27567#issuecomment-259295055
In #27567, `--dns-options` has been added to `service create/update`,
together with `--dns` and `--dns-search`. The `--dns-opt` was used
in `docker run`.
This fix add `--dns-option` (not `--dns-options`) to `docker run/create`, and hide
`--dns-opt`. It is still possible to use `--dns-opt` with
`docker run/create`, though it will not show up in help output.
This fix change `--dns-options`to --dns-option` for `docker service create`
and `docker service update`.
This fix also updates the docs and bash/zsh completion scripts.

This fix tries to address the proposal raised in 27921 and add
`--cpus` flag for `docker run/create`.
Basically, `--cpus` will allow user to specify a number (possibly partial)
about how many CPUs the container will use. For example, on a 2-CPU system
`--cpus 1.5` means the container will take 75% (1.5/2) of the CPU share.
This fix adds a `NanoCPUs` field to `HostConfig` since swarmkit alreay
have a concept of NanoCPUs for tasks. The `--cpus` flag will translate
the number into reused `NanoCPUs` to be consistent.
This fix adds integration tests to cover the changes.
Related docs (`docker run` and Remote APIs) have been updated.
This fix fixes 27921.

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.

This fix tries to add a flag `--stop-timeout` to specify the timeout value
(in seconds) for the container to stop before SIGKILL is issued. If stop timeout
is not specified then the default timeout (10s) is used.
Additional test cases have been added to cover the change.
This fix is related to #22471. Another pull request will add `--shutdown-timeout`
to daemon for #22471.

Allow passing --storage-opt size=X to docker create/run commands
for the `overlay2` graphriver.
The size option is only available if the backing fs is xfs that is
mounted with the `pquota` mount option.
The user can pass any size less then the backing fs size.
