Merge branch 'master' into develop
Added storage backend to enable google cloud storage. Added full test suite. Upgraded my google cloud storage client as I downloaded an older version by accident
Removed config from storage init method as it's simply not needed anymore. Handy whilst testing but now the test suite is in place it's kind of redundant
Improved test coverage
Added drf-nested-router package to local libs
Added entry translation api end points and full test suite
Merge branch 'develop'
