[ENG-6283] User table allows CSV and TSV downloads

[Johnetordoff]

Purpose

Allows CSV and TSVs be downloaded from the user tab on the institutional dashboard page by adding a format query param. Such as in v2/institutions/cos/metrics/users/?format=csvor v2/institutions/cos/metrics/users/?format=tsv or v2/institutions/cos/metrics/users/?format=json_file

Changes

• adds CSV/TSV renderer to view
• add .extra(size= to ensure spread sheets cover whole report, not one page.
• adds Json renderer to metrics reporter
• adds tests

looks good, yay for code reuse!

my only request would be to add a Content-Disposition header that gives the downloaded file a sensical filename

[Johnetordoff]

Maybe change format param to fix collision with normal json format?

@aaxelb There was an issue where the pagination was limiting the files to 10 items, the default page size, so I had to address that between reviews, just heads up if you are wondering about the diff.
