Support for proxy

[nicolas-f]

Hi,

You are using requests libs. There is an option to use http or socks proxy in this library.

http://docs.python-requests.org/en/master/user/advanced/#proxies

Do you have any tips in order to use ipfsapi with a proxy configuration ?

ex:

import ipfsapi

proxies = {
    'http': 'socks5://@localhost:5555',
    'https': 'socks5://@localhost:5555'
}
api = ipfsapi.connect('myserveur.org', 5002, proxies=proxies)

It isn't currently supported, but it wouldn't be difficult to add it. Right now, extra keyword arguments to the connect method are passed all the way down to here in the defaults parameter:
https://github.com/ipfs/py-ipfs-api/blob/master/ipfsapi/http.py#L59
The HTTPClient would need to check whether there were proxies defined, save them as a field (if they were), and use them when it invoked methods from requests.
@nicolas-f Would you be interested in adding this?

[nicolas-f]

Sure. I will make a PR.

Thanks

Working on this. Hardest part turns out to be lack of Multiaddr support for proxies…
