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. 
Just a tip, now you can pass an integer to the `skip_if_bz_bug_open` decorator, like `@skip_if_bz_bug_open(1117753)`
