Release of 2.0 Long-Term-Stable

This is NNStreamer 2.0 Long-Term-Stable release.

2.0's main features after 1.8 release include:
- Edge-AI capability (among-device AI) with pub/sub and query. In 2.0, this capability is an initial release without performance optimizations or feature extensions. We will eventually implement the promised optimizations and extensions with later (2.1+) versions.
- Tensor stream types updated: flexible tensors and sparse tensors are now supported. Single-tensor (other/tensor) is being obsoleted. Please use other/tensors instead.
- New H/W accelerators and AI frameworks supported
- Tensor-converter/decoder with subplugins and custom functions
- New elements: Tensor-IF, Join, Tensor-crop, Tensor-rate

+1.7.2 -> 2.0.0
+       - NNStreamer for Edge-AI
+               - MQTT Pub/Sub streams can be synchronized with timestamp values
+               - MQTT-Hybrid Pub/Sub protocol (send high-bandwidth data streams with HLS) is not included in 2.0. This feature will be enabled with 2.1+ releases.
+               - Query (workload offloading) with TCP is included as an experimental feature. Query will be updated to use MQTT-Hybrid in future 2.1+ releases.
+
+       - Stream data type redefined (backward compatible)
+               - Flex-tensor and Sparse-tensor as a format of "other/tensors".
+               - "other/tensor" is obsoleted (but will be kept supported for a while). Use "other/tensors,num_tensors=1" for single tensor stream.
+               - The conventional tensor stream is "Static-tensor", which is the default format of "other/tensors".
+               - Many elements of nnstreamer (including tensor-transform) support "Flex-tensor" as well as "Static-tensor".
+               - The MIME type is "other/tensors,format={static, flexible, sparse}". If not specified, format is static.
+
+       - Major features
+               - Flexbuf supported as subplugins of converter and decoder.
+               - LUA scripts supports as custom filters. (tensor-filter)
+               - Debian pdebuild support (tested with Sid).
+
+       - Minor features
+               - Decoder/Bounding-boxes: more options for more diverse neural net settings.
+               - SNAP+TF-Lite support.
+
+       - Fixes
+               - Tensor-filter: Python test fail, TVM bugs, code complexity, error messages, C++ exception handling
+               - Tensor-crop: region setting, timestamp handling
+               - Tizen/Family-Hub support.
+               - Yocto, MacOS build errors.
+               - ARMNN version updates.
+
 1.7.1 -> 1.7.2
        - NNStreamer for Edge-AI project started.
                - Main features of 1.8.0 release and its immediate successors will be "Edge-AI", which allows distributed on-device AI inferences.
