Dustin 2afae103d9 sensor: Set retain on config/availability messages 
When Home Assistant restarts, it puts the sensor in "Unavailable" state
until it receives an "online" message.  Since the sensor has no idea
Home Assistant is waiting for such a message, it will never send one.
By setting the "retain" flag on availability and configuration messages,
the broker will automatically resend them to Home Assistant when it
subscribes to the topic again, which resolves this issue.
