*Upgrade to pywbem v0.9.1

• Enhancements

  • Added a section “Prerequisite operating system packages” to the documentation that describes the prerequisite packages by distribution.
  • Added git as an OS-level dependency for development (it is used by GitPython when building the documentation).

• Bug fixes

  • Fixed the use of a variable before it was set in the remove_destinations() method of class WBEMSubscriptionManager.
  • Fixed a compatibility issue relative to pywbem 0.7.0, where the pywbem.Error class was no longer available in the pywbem.cim_http namespace. It has been made available in that namespace again, for compatibility reasons. Note that using sub-namespaces of the pywbem namespace such as pywbem.cim_http has been deprecated in pywbem 0.8.0.
  • Fixed a documentation issue where the description of CIMError was not clear that the exception object itself can be accessed by index and slice.
  • Fixed a documentation build error on Python 2.6, by pinning the GitPython version to <=2.0.8, due to its use of unittest.case which is not available on Python 2.6.
