[ENHANCEMENTS] add limit_rate for http proxy

[dmitriyteteruk]

Is your feature request related to a problem? Please describe.
I use Zoraxy as reverse proxy. One service behind Zoraxy is Nextcloud. I want to limit download speed from Nextcloud to avoid bandwidth problems when some users start to download big files.

Describe the solution you'd like
Nginx has option limit_rate where you can put 625k for example for 5Mbit/s speed.

Additional context
I've tried to limit speed on router level for Nextcloud virtual machine, but it applied only for virtual machine itself, and when files requested via Zoraxy - this limit does not work as Zoraxy is located in LAN and router limits are applied only on WAN->LAN connections. Also there is an option to use Linux tools on server. But Zoraxy level looks preferable as this feature may be applicable for different services behind reverse proxy.

Hey @dmitriyteteruk

Yes, this is do-able, but this can be easily workaround with multi-thread downloader software that pull multiple streams at the same time I guess?

most of users (at least in my case) will just click "Download" button on Nextcloud public page for a single file and wait for 3-5 minutes instead 1-2 minutes :)

this feature will be appreciated by admins of servers behind Zoraxy. I think it may be in same area where Rate Limit now located, something like "Bandwith limit" with description how to set 1/10/100M for example limit.
