This patch adds the ability to run `docker stats` w/o arguments and get
statistics for all running containers by default. Also add a new
`--all` flag to list statistics for all containers (like `docker ps`).
New running containers are added to the list as they show up also.
Add integration tests for this new behavior.
Docs updated accordingly. Fix missing stuff in man/commandline
reference for `docker stats`.

I disagree with #14546 that pushed the help text past 80 chars.
Aside from it now making the help text look ugly on 80 char displays,
which I use, one thing I like about the previous limitation is that it
forced us to keep our options down to more reasonable phrases/words.
For example, I think
` --disable-content-trust=true`
could have been:
` --disable-trust=true`
or even:
` --disable-ctrust=true`
But regardless, let's at least make the comments match what the code does.

While in there, modified the testing infrastructure for the help text
so that we can get commands with nested commands - like "volume".

Fixed issues related to network subcommand tests
- "network" in exempted list of short help check
- Condition for exact test modified to meet experimental commands
- Sorting of commands done in flags_experimental

Update help line to allow 90 characters instead of 80
The trust flag pushes out the help description column wider, requiring more room to display help messages.

- Making sure the exit code is always zero when we ask for help
- Making sure the exit code isn't zero when we print help on error cases
- Making sure both short and long usage go to the same stream (stdout vs stderr)
- Making sure all docker commands support --help
- Test that all cmds send --help to stdout, exit code 0, show full usage, no blank lines at end
- Test that all cmds (that support it) show short usage on bad arg to stderr, no blank line at end
- Test that all cmds complain about a bad option, no blank line at end
- Test that docker (w/o subcmd) does the same stuff mentioned above properly

delete unecessary blank after "[OPTIONS] "
and add a blank to the log between options and signature.
To make the code style consistency.

and add a testcase to catch this in the future.
While in there I also:
- removed extra periods from the few options that had them (new test)
- made the --filter option consistent across all command

estesp noticed that when $HOME is / the ~ substitutions messes up
becuase it tries to replace all paths that start with "/" with "~".
This fixes it so that it will only replace it when $HOME isn't "/".

This makes use of `%USERPROFILE%` as a substitute for
`~` on Windows and prints shorter strings for default
cert paths etc.
Also removes string escaping/quotes around default
path values printed in `docker help` command as they
are not really necessary and adds double backslashes
(\\) on windows.

As I was reworking https://github.com/docker/docker/pull/9402 I realized
that the new testcase I just added that verified all help text is within
80 characters really should be smarter and ask "docker help" for the list
of commands to check instead of having a hard-coded list. This way
it will catch "docker execwait" automagically once #9402 is merged.

This modifies the "docker help" text so that it is no wider than 80 chars
and each description fits on one line. This will also try to use ~ when
possible
Added a test to make sure we don't go over 80 chars again.
Added a test to make sure we use ~
Applied rules/tests to all docker commands - not just main help text
