Removed Alexa/AVS integration.

The integration was based on my old fork of the AVS service, which is no
longer functional given the changes the the Amazon's backend side.

A new `avs-device-sdk` is now available, but it seems that it requires
lengthy compilation processes which are RaspberryPi-specific.

Further investigation is needed for a new Alexa plugin - see #334.
