stable/kilo: testtools 2.0.0 isn't compatible with kilo

[Tony Breeds]

testtools 2.0.0 was released 2016-02-04 and has a hard requirement on on fixtures >=1.3.0 which isn't compatible with stable/kilo's
global-requirements.

We can't land an update to requirements to cap testtools as we install testtools (2.0.0) too soon and nothing we install from git in a typical devstack run requires testtools (it's only listed in test-requirements.txt) get 2.0.0.

Manually force testtools to match the desired requirements spec until we can:
1) Land the g-r patch
2) merge the update and release that in os-testr (stable/kilo)

I was trying to backport the pip_install lines to add the "-c $REQUIREMENTS_DIR/upper-contstraints.txt" to the pip command in inc/python, but this does not seem to work, in fact the version in global-requirements.txt and upper-constraints.txt do not match.

For example pbr in global requirements has <1.0, while in upper constraints has 1.2.0

[Tony Breeds (o-tony)]

@Enrico: upper-constraints.txt has no effect in Kilo. The contents of the fail are to be ignored.

Having constraints support in kilo would be awesome but it's to intrusive at this stage of kilo life-cycle
