Adding IoT Edge Module support for Pnp Bridge

[dipannita08]

Adding Pnp Bridge Edge Module support:

• Pnp Bridge core supports running as an edge module on linux gateway running Edge Runtime
• Pnp Bridge supports protocol translation for devices using adapters with linux support (Environmental Sensor, Modbus, Mqtt and Serial PnP)
• Adapter and component configuration for Bridge running as module is supported through module twin's desired property "PnpBridgeConfig"
• Bridge core reports Bridge status telemetry (Waiting for Configuration or Configuration Complete)
• Environmental Sensor adapter is now built with Bridge executable
• Client handle registration when running as module is frontloaded to receive property update for adapter configuration.

Validatation:

• Validate Pnp Bridge functionality (telemetry, properties, commands) running as Edge device using linux adapters
• Complete validation of Pnp Bridge functionality on Linux containers running in an Edge module

Please add a comment or rename to reflect this is a sample virtual sensor for illustrative purposes #Resolved

Could be a union. #Resolved

Since the adapters are re-compiled for edge module support already, and the edge/device client APIs are mostly the same, another option to consider is define a custom type for the connection handle along with macros for IoTHub<Device|Module>Client_Foo. That way the adapter code will be a little easier to read without as many runtime forks. #Resolved

Thanks for the great work. Okay to merge, just a heads-up that the MSDocs sample will need to be updated shortly to reflect the moving of the Environmental sensor sample to the main bridge project. I'll work on this.
