Installing nova-docker "disables" CLI

[Harry Kominos]

Detailed bug description:
Installing Nova docker on a compute node makes cli unusable (neutron,nova etc)

FUEL 7.0

Steps to reproduce:
Deploy compute node
apt-get install git , python-dev, python-pip,
pip install pbr --upgrade
And now from
https://wiki.openstack.org/wiki/Docker after reaching step
pip install -e git+https://github.com/stackforge/nova-docker#egg=novadocker (or by using the kilo branch)
all commands from CLI fail with error

Actual result:
root@node-23:/etc/apt/sources.list.d/src/novadocker# nova list

Expected result:
See list of vms

Additional information:
One of the packages is python-requests (2.9.1) . If i rollback to 2.2.1 (original Fuel) than I can use the CLI again.
The exact same procedure works on FUEL 6.1 with Python requests 2.9.1 without problems

AFAIK, fuel does not guarantee OpenStack will be working after "pip" manipulations. It is claimed to be working only with the MOS packages (for the 7.0 release) and UCA packages as well, in the 8.0 IIUC
