The old imports do not work with the newest rbac-client v1.3.3

Instead of 
import { BaseAPI } from '@redhat-cloud-services/rbac-client/dist/base';

following import has to be used:
import { BaseAPI } from '@redhat-cloud-services/rbac-client/base';

Let's keep the parity between old and new. Storing the output into additional /dist folder should remove the problem.
