CLI: add support for list_keymaps

List all the available keymaps for a given keyboard

Add bs4 to requirements.txt

UnicodeDammit is needed from bs4 for reading files.

Major update to work better with revisions

Find the community keymaps supported by each revision.

Get all buildable keymaps for each revision

The command now return all keymaps that's buildable for a
keyboard/revision. If the base directory of a keyboard does not contain
a 'rules.mk' file, nothing is returned. If the base directory contains a
'keymaps' directory, those keycaps will be returned for every revision.

Fix help message.

Try to figure out revision, drop -rv/--revision argument

Fix output format

Another major refactoring, add documentation

Move all useful functions to the qmk module and use the cli subcommand
as a wrapper around it.
Add both inline comments and documentation.

Add test for list_keymaps

Fix regex for parsing rules.mk files

I don't know why it couldn't put it together before... ¯\_(ツ)_/¯

Drop bs4 dependency, update docs, minor improvements

Return only the unique keymaps

Fix merging community and base keymaps

Major rework, no regex/globbing, more walking

Instead of using regexes and globbing to find the rules.mk and keymap.c
files, walk the directory tree to find them.
Also, do away with the concept of revision.

Fix commandline parsing and flake8 findings, rebase

Fixed commandline and config parsing. Thx @xplusplus.
Rebased on master and fixed merge conflicts.

Code cleanup, use pathlib, use pytest keyboard

Clean up checks and logics that are unnecessary due to MILC updates.
Use pathlib instead of os.path for readability.
Use the 'pytest' keyboard for the tests.
Add community layout for 'handwired/onekey/pytest' so we can test
community layouts.

Pathlib-ify qmk.keymap.list_keymaps()

fix list_keymaps for python 3.5
