Issue Description

Migrate Alizer from redhat-developer to the devfile organization.

Create a new repo devfile/alizer with a clone of redhat-developer/alizer, which is then marked as deprecated. Users then have to manually switch to the new import path when they want to upgrade to the non deprecated version.
