Mirroring ps docs to container ls

[sudo-bmitch]

Signed-off-by: Brandon Mitchell git@bmitch.net

- What I did

Added docs for docker container ls. This makes https://docs.docker.com/engine/reference/commandline/container_ls/ look like https://docs.docker.com/engine/reference/commandline/ps/ (including the various filter and format options).

- How I did it

Copied from docker ps docs, find and replace, and rewrapped some long lines. Ideally one command would redirect to the other.

- How to verify it

- Description for the changelog

Thanks! Yes, this is somewhat of a known issue (because there's the "old/existing" top-level commands, and their equivalent <object> <verb> variants).

I actually have two PR's to address this issue by moving the content to a "canonical" page, and redirect the other pages; that way we wouldn't duplicate the content, and make sure that they don't get out of sync. At the same time, both variants can be found in the docs (in the navigation).

PR in this repository #2389, and the associated PR in the documentation repository; docker/docs#10471

I just rebased those PR's, and you can view a preview here; https://5f751c43e0e04b000704afe5--docsdocker.netlify.app

e.g.; https://5f751c43e0e04b000704afe5--docsdocker.netlify.app/engine/reference/commandline/ps/ redirects to https://5f751c43e0e04b000704afe5--docsdocker.netlify.app/engine/reference/commandline/container_ps/

Getting this to a single file is definitely ideal. Should I go ahead and close this out, or since the reorg is still a WIP did you want to temporarily add to the clutter with this? I'll drop a comment on issues I'm seeing in the other PR.
