Add CBS monthly data collection script to crontab

[simonaho]

Add CBS monthly data collection script to crontab:

• Add CBS data to an S3 bucket - create a repo for provider code and for each year.
• Import cbs data from email and upload to AWS - nowdays importmail process is running once a week and uploads to s3 data from last 2 cbs emails
• Trigger Load CBS data from s3 when new CBS data arrives
  command to delete a certain year and load starting that year, for example 2019:
  python main.py process cbs --path <cbs dir path> --delete_start_date 2019-01-01 -load_start_year=2019
  cbs parser is in file cbs.py
  delete only data starting the year of the current files that arrived
• Create DB table versioning of emails we load from email to s3, and load new data to s3 only when new data arrives
• Modify schedule from weekly back to daily (see this pr that changed from daily to weekly)

Note that CBS processes are now in anyway-etl repo - see process repo here
