Request: Home Assistant integration

[JarbasAl]

as part of setup a number of components provide HA integration, the setup stage could prompt to install them and configure the HA access token under mycroft.conf immediately

to control HA via OVOS

• ovos-PHAL-plugin-homeassistant - bus api and GUI to control HA from OVOS
• homeassistant-skill to control the plugin above by voice

to expose OVOS in HA

• ovos-PHAL-sensors - show OVOS device in HA
• hivemind-home-assistant-notify - allow HA to make OVOS speak, this is not installed with OVOS but we want to allow the speak message in hivemind listener and generate credentials during install to be copy pasted into HA
