proxy setting not respected by lava-tool

[Benjamin Gaignard]

The proxy setting (like http_proxy environment variable) aren't respected/used by lava-tool.

A consequence is that lava-tool auth-add can't be performed below a proxy.

Output debug trace after lava-tool auth-add:

The issue seems to be located in xmlrpclib.Transport class.
We need to take care of the proxy setting when we establish the http connection

[Alexander Sack (asac)]

that seems to be an awful situation for many of our proxy locked-in assignees. atm its still ok, but once more folks pick up lava and want to use it to get one time verification of stuff this becomes a real issue.

[Zygmunt Krynicki (zyga)]

I'll get around to fix this pretty soon. I was about to improve a few lava-tool parts that have proven to be bad for end users based on the feedback so far. One of the main issues is all of the URL handling and associated error messages (they don't help). I will look at transport proxy at the same time.

You said you had some patches for this when we talked last, is it landing in time for 2011.12?

[Zygmunt Krynicki (zyga)]

Not for this cycle, I assumed it will end "later" as usual so I think this will be postponed to 2012.01

Testing of the attached branch would be massively appreciated!
