[#70162466] Remove the temporary fog files for Tools Tester

These temporary files were used to transition vCloud Tools Tester to use the new API and were required because of the circular dependency between vCloud Core and vCloud Tools Tester.

This commit removes the files and depends on a version of vCloud Tools Tester that doesn't require them.

It also bumps the version again because it changes the API (this, I believe, is the last change). Previously you could include `vcloud/fog` and also directly used the old `Vcloud::Fog::ModelInterface`. Now you cannot.
