[FEATURE REQ] Flaresolverr integration

[Flameeeeee]

Is your feature request related to a problem? Please describe.
Hi, this feature request is about integrating the Flaresolverr solution so it can be used in combination with the Generic RSS indexer type to bypass websites sitting behind a CloudFlare protection.

Describe the solution you'd like
I would like to have an option when configuring a Generic RSS indexer to specify the address of a FlareSolverr instance that will act as a proxy for every request to the RSS target. It could also be implemented in a different way like it is done in Sonarr, Radarr, Prowlarr ... With a single instance configured and tags applied to each indexer needing this proxy.

Prowlarr implementation:

Describe alternatives you've considered
I am currently using the Generic Torznab indexer which points to my Prowlarr instance which benefits from a Flaresolverr integration. However this solution is not ideal since it relies on the search engine of the indexer which takes like 2 hours to get updated with new releases compared to the RSS.

Additional context
I was using the Generic RSS indexer type for one of my indexers a few months ago but after some DDoS attacks this indexer raised his CloudFlare protection level to a point where even the RSS page is protected and inaccessible from automated systems like Autobrr or any other crawler.

Hey! Looks like you're not the only one who want this feature.

We've been planning on adding proxy support for indexer/feed downloads for quite a while so this should probably be part of that.
