pycadf should be included in requirement.txt under keystone

[yuntongjin]

keystone/notifications.py:
from pycadf import cadftaxonomy as taxonomy

so, keystone has dependency of pycadf, but pycadf is not included in requirement.txt.

How to reproduce:
When i run ./stack.sh from devstack, had an error:

2015-03-13 08:22:27.216 | File "/opt/stack/keystone/keystone/notifications.py", line 60, in <module>
2015-03-13 08:22:27.216 | 'group': taxonomy.SECURITY_GROUP,
2015-03-13 08:22:27.216 | AttributeError: 'module' object has no attribute 'SECURITY_GROUP'

The reason is that global-requirements.txt has pycadf>=0.8.0 and the version of it on my box is 0.7.
after include it in keystone requirement, the pycadf will be upgrade to 0.8 according to global-requirements.

Is there a patch up for this?

[Morgan Fainberg (mdrnstm)]

Keystone already has 0.8 in the requirements. This might have just been a lag between global requirements update and keystone accepting it:
