Semantic Conventions - script to automatic generation of semantic conventions c++ code

[lalitb]

As part of #868 and #872 , currently we are embedding semantic convention attributes manually into C++ code. This can be automated.
This ticket is to check the feasibility of automatic generation of C++ code from semantic convention YAML data model using Jinja template engine.
