Error getting version in ec2-api repo

[Alfredo Moralejo]

When running python setup.py --version on master branch (Commit 64a3772) I get following error:

]$ python setup.py --version
ERROR:root:Error parsing

error in setup command: Error parsing /tmp/ec2-api/setup.cfg: ValueError: git history requires a target version of pbr.version.SemanticVersion(9.0.1), but target version is pbr.version.SemanticVersion(9.0.0)

Root cause is conflict between pbr discovered version (9.0.1.dev6) and the one set in setup.cfg (9.0.0). It's also happening in stable/train.

    Remove version attribute from setup.cfg

    This project uses pbr so it uses git tags and Sem-Ver pseudo header in
    commit messages. Having versin setup.cfg can lead to conflicts and
    errors when trying to get the package version using setup.py --version.

    Note that pbr provides the Sem-Ver "magic" works to bump releases
    without adding a tag [1].
