Python 3 fixes in L1 menu generation (!30898) · Merge requests · atlas / athena · GitLab

Joerg Stelzer requested to merge stelzer/athena:master-ATR-21075 into master Mar 05, 2020

filter method behaves differently in python 3 (can be called only once)
dictionaries key order follows insertion
json dump separators explicitly specified to create uniform behavior As a result L1 menus generated in python 2 and python 3 are now identical

Closes ATR-21075
