packaging and CI refactor

[stavxyz]

Among other things, this change adds a circle.yml file so we can start testing airbrake-python using CircleCI which is free for open source projects like this one.

The python versions I have configured for testing are:

• 2.7.9
• 2.7.10
• 3.3.3
• 3.4.3
• 3.5.0

I have a passing CircleCI build on my fork against the code in this pull request: https://circleci.com/gh/samstav/airbrake-python/12

In order to use CircleCI, an owner on this repo will need to go here and allow the project to be tested: https://circleci.com/gh/airbrake/airbrake-python

@kyrylo Any chance you could have someone from the team review? Been waiting on a merge for this for a while. Thanks!

[kyrylo]

Hey! Thanks for the reminder. Never hesitate to ping, you are always welcome :)

We'll review this ASAP (which is probably tomorrow or during this week).

@kyrylo If you are cool with testing in CircleCI, an owner will need to go here and choose to "follow" the project: https://circleci.com/gh/airbrake/airbrake-python

@samstav 👍 on the tox + circleci additions. LGTM

@kyrylo LGTM.

@vmihailenco want to give this a one over when you have a moment?

I think I enabled CircleCI, but it fails https://circleci.com/gh/airbrake/airbrake-python/1

@samstav
@kyrylo If you are cool with testing in CircleCI

That's our preferred way! :)

Looks like its circle trying to infer how to run tests. Will work with @samstav to try to get things going more as intended.

Thanks getting the ball rolling.
