v0.23.alpha

v0.23.alpha provides new services and support for IoT Messaging and Module Deployment:

Release highlights:

• New ODE Action to add ODE occurrence data as NvDsEventMsgMeta to the NvDsFrameMeta on ODE occurrence (see #700)
• New IoT Message Sink to convert the NvDsEventMsgMeta to an IoT message payload and to send the message to a remote entity using a specific message protocol.
• New "Message Broker API" that supports both unidirectional (device --> client) and bidirectional (device <--> client) messaging (see #703).
• New GitHub repository with Dockerfile and utility scripts to support IoT module deployment (see #709).
• Updates to the make and install process to better facilitate application development and deployment (see #710, #720, #712, #710).
• New "Info Services API" to help monitor and debug deployed Docker images (see 723).

Important the IoT messaging support is very preliminary - released so others can contribute on more testing and setup documentation for the various Messaging Protocol Adapter Libraries. More complex examples such as messaging captured images and custom payloads need to be developed.

Note: the binary attached to this release is built for Jetson on DeepStream 6.0.1
