feat(client): Add system proxy support for macOS #172

[andrzejSulkowski]

cc hyperium/hyper#3850
continued work on PR Draft #171

Because the "system-proxies" introduced quite a few lines of code, I decided to split the matcher.rs into multiple files (builder.rs, matcher.rs, no_proxy.rs, utils.rs)

• Introduced setter methods for the Builder
• MacOS System Proxies
  - [ ] Windows System Proxies

Windows System Proxies should be implemented by someone who is using Windows or has a VM to impl. and test the code.

re-open of #172

[seanmonstar]

Thanks for re-opening. I tried to make use of this, but I ran into some issues. There were some fairly big merge conflicts, some changes to documentation, and a refactor into many files all included. While I'd welcome discussing any of those, it was hard for me to merge.

So, I created #189 that copies over just a couple functions from reqwest, and otherwise doesn't re-organize the structure.

Is there anything I can do to help here out. Its a while ago when I worked on this the last time but I could fairly easy get again into the code and look into some issues which came up.

Otherwise we can close this and move on with our lives :)

[seanmonstar]

I think some of the most useful parts that are still in this branch are the unit tests. Add an inner mac::tests module that tests out a slightly refactor merge_store using a CFDictionary could be helpful.

Up to you, if you want to submit those, feel free to open a new PR with just those changes. Thanks!

Could you be please more specific?
