Support passing proxy authentication to FlareSolverr

Is your feature request related to a problem? Please describe

The problem is that I'm in a country where indexers like 1337x.to are blocked.

While this is an easy problem to solve knowing that I have a NordVPN subscription, I can easily use my account to enable a Socks5 general proxy in prowlarr but the problem is that 1337x.to now has a cloudflare protection.

To solve the cloudflare problem, I had to use FlareSolverr as stated.

FlareSolverr is not using the general proxy defined in prowlarr which leads back to the first problem of 1337x.to is blocked in my country.

I checked the code that is related to the proxy to FlareSolverr and it's explicitly stating to ignore the proxy if there is a username and password which is the core of the problem

var proxyUrl = proxySettings != null && proxySettings.Username.IsNullOrWhiteSpace() && proxySettings.Password.IsNullOrWhiteSpace() ? GetProxyUri(proxySettings) : null;

Describe the solution you'd like

I would like for the prowlarr to actually send the username and password of the proxy to flaresolverr because flaresolverr explicitly supports that. @

Describe alternatives you've considered

I have considered using a docker vpn container like GluetunVPN and then changing the default gateway for flaresolverr to go through the VPN but it's not a straight forward operation and the whole problem could be easily solved.

Anything else?

FYI docker supports quite easily a proxy by passing some envs:

docker run \
    -e HTTP_PROXY=http://username:password@proxy2.domain.com \
    -e HTTPS_PROXY=http://username:password@proxy2.domain.com \
    flaresolverr/flaresolverr

First of all, thank you for the fast response and the quick implementation. Appreciate it.
Regarding the HTTPS_PROXY, I didn't know that docker supports that natively, I was looking into flaresolverr environment variables to find something like this.
Thank you again !
