Description of problem: Currently the bkr command uses the "~/.beaker" file for saving user configuration. As there are more beaker tools expected to have a config files stored somewhere it would be nice to have them together in a single place (dir). For example current rhts-wizard now saves user preferences in .rhts/wizard. Future workflows may want to save some of the default values on similar place. Let's create a common .beaker folder where all config files will be placed.
I implemented ~/.beaker_client/
