Initial zwave_js support

[raman325]

Proposed change

WIP support for zwave_js. Requires upstream support in HA, some changes to zwave-js-server-python, and a more thorough review, but I wanted to get a draft out there so you could get an early peek at the logic and provide feedback.

TODO:

• Add tests
• Look at reducing repeat code by building more helpers
• Add a new asset to create allow_execution for zwave_js
• Verify that all of this actually works once zwave_js is live

Type of change

• Dependency upgrade
• Bugfix (non-breaking change which fixes an issue)
• New feature (which adds functionality)
• Breaking change (fix/feature causing existing functionality to break)
• Code quality improvements to existing code or addition of tests

Additional information

Here's hoping zwave-js handles code slots better than ozw 👍

@firstof9 does release drafter have to be installed before this can be merged?

[raman325]

This can't be merged until the next HA release at a minimum, it won't work until that happens

The release drafter stuff only deals in the workflow stuff for github, nothing that would halt a merge.

Tests will fail until 2021.2.0 drops.
