add proxy support

Add proxy support for http client

[vans163]

Does this support username+password? Also this is HTTP proxy only?

[antonioua]

this proxy is for http client only, doesn't support username/pass but I can try to add it @vans163 .

@antonioua can we use SOCKS5 proxy as well? not exactly sure if used http client would work with them

[antonioua]

yep, tested socks5 and http - both works.

docker network create tor
docker run --rm -tid --name mytor --network tor -p 9050:9050 -p 8118:8118 -e LOCATION=US dperson/torproxy
docker run -ti --rm --network tor -e BOMBARDIER_PROXY="socks5://mytor:9050" xdesigns/bombardier:0.0.1 -c 1000 -d 10s -l -m GET https://httpbin.org/get

saw another PR master...mariotrucco:78-add-proxy-support for proxy support, that one assumes it can only be a http proxy, but otherwise looks reasonable as well

Yea I think its important to have user/pass auth for both http and socks5 proxy as most paid proxies use that. Free/open/tor proxies dont but those are very few.

Note: HTTP Auth can be done like http://username:[email protected]:9050/

[sebastienros]

Should probably come from a command line argument

[antonioua]

done

[antonioua]

added proxy http/socks5 support for both http and fasthttp clients
