With this, `docker pull deb<tab>` will show all `debian:*` tags, as before, but `docker pull -a deb<tab>` will complete directly to just `debian`. 👍

Right now devicemapper mounts thin device using online discards by default
and passes mount option "discard". Generally people discourage usage of
online discards as they can be a drain on performance. Instead it is
recommended to use fstrim once in a while to reclaim the space.
In case of containers, we recommend to keep data volumes separate. So
there might not be lot of rm, unlink operations going on and there might
not be lot of space being freed by containers. So it might not matter
much if we don't reclaim that free space in pool.
User can still pass mount option explicitly using dm.mountopt=discard to
enable discards if they would like to.
So this is more like setting the containers by default for better performance
instead of better space efficiency in pool. And user can change the behavior
if they don't like default behavior.

Retry was kind of extracted from wait_until_reachable. The goal is to be
able to wait for a command to succeed, or fail if it doesn't succeed
after a defined number of attempts.
Indirectly improve the error logging: the output of the retry command
won't show up unless it constantly failed.

The cluster configuration is now embedded into the container. It's
guaranteed to be correct (as in, generated by BuildContainerConfig) at
all times.

- Add sed to Dockerfile; this sed exists on publish script; breaks headings/nav in files without metadata
- Ensure sed runs over storage-driver/ subdir
- Add metadata to all the files (including specs) that don't have it; this ensures they display correctly on publish
- Implement the fix for the showing up in Github
- Update template with GITHUB IGNORES

Minor thing but docker cp --help was:
Copy files/folders from a PATH on the container to a HOSTDIR on the host
running the command. Use '-' to write the data
as a tar file to STDOUT.
This changes it to:

The \n made the output look funky.
