Title:
  Tox exhausting /tmp partition

Status in Keystone:
  Fix Released

Bug description:
  So every time i tried to run tox i was getting the error message that
  /tmp was out of space when trying to create the virtual env which
  means that creating the virtualenv was filling a 3gb partition.

  In our tox requirements we currently have:

  deps = -r{toxinidir}/requirements.txt
         -r{toxinidir}/test-requirements.txt
         .[ldap]
         .[memcache]
         .[mongodb]

  By having each of those additional dependencies listed as .[XXX] tox
  is installing . (the keystone working directory) into a virtualenv
  then determining the entry point. This created 3 seperate /tmp/pip-
  XXX-build directories. The other side of this is that my
  keystone/.testrepository folder is now 994M so when tox copied this to
  tmp 3 times and then tried to install all the dependencies it doesn't
  leave much space.

  There are two fixes to this: 
  1. reset my .testrepository database
  2. dependencies should be listed together like .[XXX,YYY,ZZZ] so . is only copied once

  As an addition to this because we are installing dependencies with
  .[XXX] which means install . (working directory/keystone) + XXX
  dependencies there is no reason to specifically install -r
  requirements.txt as this will be handled for us.
