[ddonahue007]

Closes: https://issues.redhat.com/browse/COST-2136

Testing:

• setup Nise like you would normally

  > mkdir my_reports
  > cd my_reports

- For AWS generation:

> nise report aws-marketplace --start-date 2020-12-01 --end-date 2021-01-27 --write-monthly 
> ls
December-2020-marketplace.csv 
January-2021-marketplace.csv

Validate by doing a search for 'AWS Marketplace' in the above files

You can also use the following to build out reports

> nise report aws-marketplace --start-date 2020-12-01 --end-date 2021-01-31 --write-monthly --aws-s3-report-name None --aws-s3-bucket-name ~/Desktop/myBucket

- For Azure generation:

> nise report azure --version-two --start-date 2020-12-01 --end-date 2021-01-27 --write-monthly 
> ls
costreport_f240d1d6-8007-4a35-bb60-92696c01e140.csv
costreport_b77526da-8420-4c12-b14f-21e1d61a3ac7.csv nise_azure.csv
