V0.1.2 - Docker Support and other misc changes

[raetha]

The changes included are:

• Allowing an easy Docker build process with persistent config and modified folder structure. (if you accept this, you'll want to update git location in Dockerfile)
• Use of original Kevin Vincent wyzesense_custom.py within Docker image, rather than modified version.
• File based logging at the wrapper level (wyze-mqtt.py)
• Minor tweaks to the paho-mqtt library calls to match their documentation and possibly help with the eventually failing MQTT connection.
• Make JSON variables more compatible with Home Assistant by removing spaces in the names.
• Home Assistant MQTT discovery support

Feel free to not accept any of this, or just borrow things. I just struggled to get this working in Docker on a RPi and figured I would share back.

I've completely reworked what I was trying to accomplish and fleshed out HASS discovery support, error handling, etc. At this point this pull request doesn't really make sense. If you'd like to look at my upcoming build, please check the v0.5 branch. I'm getting some code review and then plan to push it to master replacing the old version entirely.
