Deleting a cv associated to ak, shouldn't delete ak

- Updated the locator to check the progress bar while publish/promote CV
- Added a new fn `delete_version` to delete CV version from all envs
- Added support to move the entities associated to CV version to other env and CV, currently moving  default to 'Library' and 'Default Organization View'
- Added test `test_positive_delete_activation_key_6` to test  this functionality and for now its blocked with bz 1117753

Please note that the functionality to remove a CV version from specific env is still not implemented. I'll do that in another PR as related issue is already opened. 
Better to use the entire 80 characters line, also will make better to read.
