In particular values starting with the `$settings` prefix should be mapped
based on user-configured preferences in the app. (Note also that this is
currently an experimental feature that we may change in the future.)
In reality there are two different views onto an OONI Run link descriptor. One
is the view from the perspective of the creator and owner of the link, the
second is from the perspective of measurement applications that need to consume
these links.

The reason for this is that certain target lists need to be generated
dynamically and at runtime, while the parameters for generating these dynamic
links are specified by the creator of the link.

Currently the following `$settings` are defined:
A prime example of this would be the OONI Run link for the stock OONI Websites
card. The OONI Run descriptor, as specified from the link creator, is saying
"run the test-lists with weights applied based on coverage", while the mobile
application will then receive a prioritized and sorted list which will change
every time a new run is performed.

* `$settings.category_codes` should be replaced with the list of category codes
the user has enabled (ex. `["HUMR", "NEWS"]`.
To achieve this we need 2 different views on the link, one for the creation
phase (`target_name`) and another for the retrieval phase (`targets`).

Based on the above specification it would be possible to re-implement the cards for the OONI Probe
dashboard as follows.

Upon receiving this request, the OONI Run backend:

1. SHOULD check whether the `${oonirun_link_id}` exists and return 404 if it does
not.

2. if everything is okay, returns `200` to the client (see below).

A client should also include the following headers to allow the server to
properly generate dynamic target lists:

* `X-OONI-ProbeCc`: Two letter, uppercase country code (eg. IT)
* `X-OONI-ProbeAsn`: ASN, two uppercase letters followed by number (eg. AS1234)
* `X-OONI-Platform`: platform name (eg. android)
* `X-OONI-SoftwareName`: software_name (eg. ooniprobe-android)
* `X-OONI-SoftwareVersion`: software_version (eg. 3.14.0)
* `X-OONI-NetworkType`: flag used to indicate the network type where the
measurement is run: 0 unknown, 1 for wifi, 2 mobile
* `X-OONI-Charging`: 1 yes, 0 no. Set only for devices with batteries.
* `X-OONI-RunType`: 1 timed, 0 manual
* `X-OONI-WebsiteCategoryCodes`: comma separated list of category codes that user has chosen to test (eg. NEWS,HUMR)

### Response body

In case of success (i.e. `200` response), the OONI Run Service MUST return the
following JSON body:
