Bug Description

Before Kilo, Ceilometer has been used single-threaded wsgi-server. This bug is created to track backports of multi-threaded implementation from Kilo (MOS 7.0) to other MOS versions.
Multi-threaded implementation provides more stability. Single-threaded implementation along with the bug https://bugs.launchpad.net/mos/+bug/1510083 makes Ceilometer not usable at all. Multi-threaded implementation may become easily broken without the fix for https://bugs.launchpad.net/mos/+bug/1510083 as well, but this should be done on purpose. Single-threaded implementation on real env becomes broken after 3 simple API requests

Please don't change bug importance due to the fact it was found at customer site - just adding customer-found tag is enough. We would like to have Importance field to reflect actual impact of the issue.

The status is High indeed. Ceilometer-api cannot be used in production without this patch because API stops responding after 3 heave requests.

Fix bug with stucked requests on api service

Currently ceilometer api have a one thread and doesn't
interrupt request after client connection interrupting.

So, in current CR this issued behavior is fixed.
