Add plugins for Arris Cable Modem SB6183
This provides two plugins: * arris-sb6183 - Power levels, SNR, error counts * arris-sb6183_uptime - Uptime in days These are two seperate plugins because it's two different urls it needs to hit, and this seemed simpler. arris-sb6183 provides multigraphs for each channel.
