make Adafruit reconnect optional
make Adafruit reconnect optional

It is off by default. Can be turned on in config YML:

notifiers:
    adafruit:
        username: me
        api_key: my-api-key
        reconnect: true

Reconnecting doesn't always work. I find it more useful to let the client
crash and be restarted automatically by runit.
