Merge pull request #8870 from photoninger/spacewalk_organizations

Add support for multiple organizations in spacewalk.

+# To limit the script on one organization in spacewalk, uncomment org_number
+# and fill in the organization ID:
+# org_number=2
+
+# To prefix the group names with the organization ID set prefix_org_name=true.
+# This is convenient when org_number is not set and you have the same group names
+# in multiple organizations within spacewalk
+# The prefix is "org_number-"
+prefix_org_name=false
