Add proxy support when running fetching timing metrics

[soulgalore]

I've missed added the newly added proxy support in BT, right now proxy only works when analysing against the rules.

Any plans when the proxy support will be added? I'm facing this problem at the moment when running sitespeed.io behind our company proxy.

Hi @moritzzimmer I could have a look at it tonight, it has support so it will hopefully be easy to fix. If you run without fetching Navigation User Timings, it should work with a proxy.

no looks broke when using cUrl, yep, I will have a go at it tonight.

[moritzzimmer]

awesome! Fetching without navigation user timings works flawless

[soulgalore]

fixed in 2.6-wip, will probably do a release tonight :)

@moritzzimmer this is for a proxy that doesn't require authentication, right? Browsertime only supports proxies without username/password at the moment.

fyi no release tonight, aiming for tomorrow. @tobli I verified the whole proxy flow (without l/p), I've never tried that on either of components.
