Cost Explorer is awesome but it could be even better: users want to compare arbitrary periods of time, which we are not able to at the moment.

This feature consists of 2 epics:

1. Cost Explorer goes from 90 days of data to 15 months of data. Rationale: users want to compare quarter-over-quarter and even year-over-year.
2. DONE Give users a date picker which allows them to choose arbitrary dates (any day) as start and end of report. Rationale: billing and reporting cycles vary wildly across organizations and industries, sometimes due to regulations others due to internal policies, so "show me this natural month" (i. e. from June 1 to today June 8), "show me the past 3 months" (full April, full May and part of June), etc might be interesting but not useful

OLD DESCRIPTION, FOR HISTORICAL REASONS

Show services and costs in a multiple month view.

Similar to what cloud cost management products do: showing a stacked list of services and their costs that span several months.

The customer will be able to select:

• time interval (1 month, 3 months, 6 months, 12 months) DONE
• time interval as start and end dates
• services shown in the graphic from a drop down list
