WSGI for st2auth and st2bundle

[arm4b]

Let's open PR, since almost all blockers resolved with no need of unix sockets anymore and we can commit, rather then experiment/try & force-push.

Addresses issue #94

Most of the work is done by @enykeev

@armab I'd say we're ready to merge. If it looks fine to you, merge it and I'm going to test it across all the platforms from bintray tomorrow.

Looks nice ;)

Let me debug a little (CircleCI + SSH).

If timeout increase worked (stable), then we should better hardcode it in st2-packages internal files, without touching circle.yml.

To avoid touching circle.yml in st2 repo.

Regarding failed build: https://circleci.com/gh/StackStorm/st2-packages/262

I could run tests with ST2_WAITFORSTART=1 for 10 times in a row in CircleCI + SSH environment, so couldn't reproduce it.

docker-compose -f docker-compose.circle.yml run -e ST2_GITURL=https://github.com/StackStorm/st2 -e ST2_GITREV=master -e ST2PKG_VERSION=1.4dev -e ST2PKG_RELEASE=8 -e RABBITMQHOST=172.17.0.1 -e POSTGRESHOST=172.17.0.1 -e MONGODBHOST=172.17.0.1 -e ST2_WAITFORSTART=1 wheezy test

Let's merge, but if it appears once again - what we can do in future to debug better - share /var/log/st2 logs and service logs via Circle artifacts, to read these files once something wrong appears (could be a good idea in any way).

Good to know, that even with 0 timeout it worked well:
https://circleci.com/gh/StackStorm/st2-packages/268

See this build: https://circleci.com/gh/StackStorm/st2-packages/268
where I accidentally set timeout to 0, described here: #105

@enykeev , @armab this is inappropriate, there's a config file which is meant to be customized. You make it static by hardcoding the path to the default same way it was before.

Good way is:

1. make, say it, /etc/st2/config.
2. place the file there

So the enduser can get control of it.
What do you think?

[enykeev]

gunicorn does not allow you to pass arguments the same way you're passing them to the script. You can although redefine config pach using env variable https://github.com/StackStorm/st2/blob/master/st2api/st2api/gunicorn_config.py#L35-L36. I don't see it as an immediate concern, the amount of users who need to change the config is extremely low, but if you believe this is a problem, feel free to pass the variable.

+1 @enykeev

In this special case like it more too, comparing to config file.
And path is already hardcoded in many other startup scripts, don't see any inconsistencies here.

[dennybaa]

yep. that's right I agree. thanks for clarifications.
