Feature request: Cloudflare cache flush API integration

[FinnSandbeck]

Issue description

Currently, Cloudflare cache can only be managed by Time To Live (TTL) or by purging all cache via the Umbraco cloud administration panel. It would be helpful if there were access to this through Umbraco API. For some of our clients, this is a bit too limiting, so they opt not to have full Cloudflare page caching enabled.

1. Integrate a function to purge all cache from Cloudflare via code
   This would be useful to tie this call to the publish function or a custom button in the back office, so you don't have to go to the Umbraco Cloud administration panel to manage this.
2. Integrate a function to purge the cache for a specific item/page via code
   This could be tied to the publish event, to ensure that the effected page cache would be regenerated when new content is available.
