Pep8 1.4.6+ new warnings

[Dirk Mueller]

Pep8 1.4.8 fixed a few bugs in the pep8 checks that would trigger frequently when used on OpenStack:

  * Correctly report other E12 errors when E123 is ignored. (Issue #103)
  * Accept both styles of closing bracket indentation for hanging indent.
    Do not report error E123 in the default configuration. (Issue #103)
  * Fix E701, E702 and E703 not detected sometimes. (Issue #196)
  * Fix E122 not detected in some cases. (Issue #201 and #208)

Various code in OpenStack needs to be updated to be passing against pep8 1.4.6+ in order to be able to raise the version requirement.
