Make automatic process for the weekly dates parameters generation.

[zimzoom]

Context:

• Once a week, the Logic App calls the scraper by iterating over a list of parameters. The scraper is called with "start date" and "end date" parameters -- the Logic App calls it using 2 week increments, going back 5 years. This means that this list of date parameters needs to be re-generated every week.
• Currently, the Python script that generates the array of data parameters is run manually on a dev's computer. It creates a json file, which is then manually uploaded to a specific container that the Logic App reads from.

Goal:

• This needs to be an automated process rather than something that is run manually. The recommended way is: create a new Azure Function with a "timer trigger", set to go off once a week, that generates logic-app-dates.json and writes it to the container "logic-app-resource" (next to "case-html").
• No changes need to be made to the Logic App, as long as it results in a json file with the same name, in the same container, with the same structure. ( [["2018-04-25", "2018-05-01"], ["2018-05-02", "2018-05-08"], ...(etc to present)... ]
• Contact Luci for the dates generator python script and example json file.
