Sean Mooney d71d2dc219 introduce global greenpool
This change add a global greenpool which is used to manage
the greenthreads created via nova.utils.spawn(_n).

A test fixture is also added to use an isolated greenpool
which will raise an exception if a greenthread is leaked.
the fixture will optionally raise if greenlets are leaked.
This is enabled by unit test by default and is configurable
for functional tests.

This change removes all greenthread leaks from the unit
and functional tests that were detected. 7 functional
tests still leak greenlets but they have no obvious
cause. as such greenlet leaks are not treated as errors
for funtional tests by default. Greenthread leaks
are always treated as errors.
Set NOVA_RAISE_ON_GREENLET_LEAK=1|true|yes when invoking
tox to make greenlet leaks an error for functional tests.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:

Developers
