havana (2013.2) prepare breaks due to verision confict on pbr

[Ivan Melnikov]

When anvil master is used to install OpenStack from havana-2013.2.yaml, prepare action fails on download stage. Specifically, egg_info on hacking older hacking version is not run because of version conflict on pbr (it requires pbr < 0.6, while at that moment we already have pbr 0.7 in anvil's virtualenv).

Newer pbr was probabliy brought by keystoneclient and glanceclient from optional-requirements.txt.

Hmmm, that sucks. Maybe we should reconsider that branch strategy again, problems like this wouldn't exist if we just had a branch that could install the right version.

[Ivan Melnikov (imelnikov)]

I think if we have branches like we used two, we would drop 2013.2 support long time ago, right after 2013.2.1 release. Maybe that's what we'll have to do -- just remove havana-2013.2.yaml. We are not going to support all OpenStack releases forever anyway.

Another option would be to postpone installing of keystone and glance client to prepare stage, when origins is already known, and install versions of clients mentioned there if if origins specify exact tag. Let me try that.

[Joshua Harlow (harlowja)]

Sounds ok, shouldn't be hard, or install only when needed (even later than the prepare stage...)

    Allow venv access to system packages

    - Adjust the virtualenv creation so that the created venv
      has access to the system (parent) packages so that when
      clients are installed anvil will have access to them to
      do post-start actions.

    Fixes bug 1294653
