Device disconnects not detected

[onionhammer]

This is related to #101, since downloading the code, creating my own nuget packages and publishing them to my own repo solves this, but because off #101, this fix cannot be downloaded because dotnetty dependencies are out-of-band between the protocol gateway nuget packages.

When I break an MQTT client/device connection, the disconnect is never relayed to the IOT hub via the protocol gateway UNLESS I update the storage package which depends upon dotnetty-signed nuget packages AND remove and reinstall dotnetty (to the non "-signed") versions.

Please, please please update your storage provider nuget package. For now I'm switching to forked protocol gateway nuget packages since it's apparent that nobody here will keep these packages up-to-date.
