Improve MQTT behavior and add experimental parsing for color temp support from Plejd API (#298)

* Update underlying docker containers and dependencies.
* Minor linting and code issues fixes
* Update supported devices section
* Improve Mqtt message properties - retain, etc.
- Retain discovery messages
- Don't retain others
- Set QoS to 1 consistently to ensure at least once delivery
- Set session timeout to ensure a reasonable TTL on messages
* Code and logic to remove any retained mqtt messages for SET/STATE/AVAILABILITY
* Temporary restructure of init flow for mqtt.
- No longer wait for HA birth message
- Don't listen to incoming messages until old retained messages have been purged.
- More details in https://github.com/icanos/hassio-plejd/issues/218
* Fix lingering incorrect access of connectedDevice.id
* Fix to avoid Home Assistant setting retain flag on MQTT SET STATE messages
* Parse new TRAIT=15, assuming this means dimmable and tunable white
* Clarify TRAITS bitmask values
* Add experimental parsing for color temp support from Plejd API
* Lint fixes
* Remove null coalescing operator since we don't compile code
* Handle case where outputSettings is null in PlejdApi
* Solve MQTT errors due to deprecated api color_temp and unsupported removal of retained state messages
