[5.x] Telemetry

[duncanmcclean]

This pull request introduces anonymous telemetry into Simple Commerce.

Every 30 days, in production, Simple Commerce will send an API request to my backend, with the following information:

• Site Hash, based on your APP_URL (so I can identify telemetry to a specific site, but without knowing the site's domain)
• Statamic / PHP / Simple Commerce versions
• Number of orders made since the last telemetry request
• Total of orders made since the last telemetry request (let's me do things like "Simple Commerce processes £xxx of orders every month").

Opt-out

All of the data sent to the API is anonymous and can't be tied back to your site. However, if you wish to opt-out, you may add the following setting to your config/simple-commerce.php file:

'enable_telemetry' => false,
