Avalon Graphene python worker open issues

[manojgop]

• Avalon Graphene Python worker has generic classes for worker encryption, signing and hash calculation. These files should be moved to Avalon repo. Avalon crypto utils/Avalon SDK should be restructured and packaged so that python worker can install Avalon SDK. Avalon Python worker will be able to build independent of Avalon core framework if we have a Avalon SDK package which can be installed using pip (for example, pip3 install python3-avalon-sdk)

• Read python worker details from configuration file.

• Enhance exception handling in Avalon Python worker.

• Graphene Production blockers: https://github.com/oscarlab/graphene/issues/1544

• Graphene SGX Python worker initially takes more than 3 minutes to load and get ready to accept work order request. This will be optimized later by Graphene-SGX.
