created draft for generic analysis method

Summary

This introduces a module that handles calling of scripts in the server side backend.

Focus

generic_analysis.py and example_script.py

Test Environment

Please check the integration tests and also do the following:

• Create an Instance with the appropriate data model (or use CFAED local-scripting)
• add the example_script as SSS in bin directory
• make sure this branch is used in advancedtools
• create a dummy script that calls run(ENT_ID) (or use update_changed_entities.py from CFAED) and setup logging (e.g. like this debug_file = configure_server_side_logging(loggername="") )
• call the script (e.g. resp = run_server_side_script('update_changed_entities.py'),print(resp.stdout, resp.stderr) )
