Send dtoi param with usage ping

Description

Each browser will need to store the YYYY-MM-DD encoded local date of installation. For the 14 days after installation, the usage ping should include a ‘dtoi’ entry containing the date of installation. After the 14 day period is over the ‘dtoi’ should be sent as null.

Example: The browser is installed on May 1st, 2020

For the dates including May 1st to May 14th, the usage ping should include the attribute 'dtoi': '2020-05-01'. For all days after the 14th of May the usage ping should send 'dtoi': null. Nothing else in the existing usage request body should change.

Test Plan:

1. Open network sniffing tool (Charles, Wireshark)
2. Ensure that the browser sends a request to https://laptop-updates.brave.com/1/usage/brave_core with query parameter set to the current date
3. Move system clock forward 14 days and see that this parameter is sent up as null.
