Improve version tracking tool

[dchassin]

• [x] Finish update.py script so it gather log data daily and stores it permanently in the S3 bucket to long term storage
• [x] Add daily call to update.py to collect logs, generate graphs, and cleanup

Daily data collection should tabulate and graph the following and store these in https://version.gridlabd.us/logs/

• [ ] Daily usage (MM/daily.csv and MM/daily.png)
• [ ] Monthly usage (YYYY/monthly.csv and YYYY/monthly.png)
• [ ] Daily usage of branches (YYYY/MM/daily_branch.csv and YYYY/MM/daily_branch.png)
• [ ] Daily usage of branches by unique users (YYYY/MM/daily_user.csv and YYYY/MM/daily_user.png)
• [ ] Monthly usage of branches (YYYY/monthly_branch.csv and YYYY/monthly_branch.png)
• [ ] Monthly usage of branches by unique users (YYYY/monthly_user.csv and YYYY/monthly_user.png)
• [ ] Update insights tool so it uses results of update.py in logs.
